###### Securities and Exchange Commission

          - [Release No. 34-99288; File No. SR-CboeBZX-2023-028]

                    On April 25, 2023, Cboe BZX Exchange, Inc. (“BZX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to list and trade shares (“Shares”) of the ARK 21Shares Bitcoin ETF under BZX Rule 14.11(e)(4), Commodity-Based Trust Shares. The proposed rule change was published for comment in the                     **Federal Register**                     on May 15, 2023.[3]                                          On June 15, 2023, pursuant to section 19(b)(2) of the Act,[4]                                          the Commission designated a longer period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change.[5]                                          On June 28, 2023, the Exchange filed Amendment No. 1 to the proposed rule change, which amended and replaced the proposed rule change in its entirety. On June 30, 2023, the Exchange filed Amendment No. 2 to the proposed rule change, which amended and replaced the proposed rule change, as modified by Amendment No. 1, in its entirety.

## I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

                    Cboe BZX Exchange, Inc. (the “Exchange” or “BZX”) is filing with the Securities and Exchange Commission (“Commission”) a proposed rule change to list and trade shares of the ARK 21Shares Bitcoin ETF (the “Trust”),[8]                                          under BZX Rule 14.11(e)(4), Commodity-Based Trust Shares.                

                    The text of the proposed rule change is also available on the Exchange's website (                    *http://markets.cboe.com/​us/​equities/​regulation/​rule_​filings/​bzx/​*), at the Exchange's Office of the Secretary, and at the Commission's Public Reference Room.                

## II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements.

### A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

This Amendment No. 5 to SR-CboeBZX-2023-028 amends and replaces in its entirety the proposal as originally submitted on April 25, 2023 and as amended by Amendment No. 1 on June 28, 2023, Amendment No. 2 on June 30, 2023, and Amendment No. 3 on July 11, 2023, and Amendment No. 4 on October 24, 2023. The Exchange submits this Amendment No. 5 in order to clarify certain points and add additional details to the proposal.

                    The Exchange proposes to list and trade the Shares under BZX Rule 14.11(e)(4),[9]                                          which governs the listing and trading of Commodity-Based Trust Shares on the Exchange.[10 11]                      21Shares US LLC is the sponsor of the Trust (the “Sponsor”). The Shares will be registered with the Commission by means of the Trust's registration statement on Form S-1 (the “Registration Statement”).[12]                                          As further discussed below, the Commission has historically approved or disapproved exchange filings to list and trade series of Trust Issued Receipts,[13]                                          including spot-based Commodity-Based Trust Shares, on the basis of whether the listing exchange has in place a comprehensive surveillance sharing agreement with a regulated market of significant size related to the underlying commodity to be held.[14]                                          Prior orders from the Commission have pointed out that in every prior approval order for Commodity-Based Trust Shares, there has been a derivatives market that represents the regulated market of significant size, generally a Commodity Futures Trading Commission (the “CFTC”) regulated futures market.[15]       ( print page 2389)                        Further to this point, the Commission's prior orders have noted that the spot commodities and currency markets for which it has previously approved spot exchange-traded products (“ETPs”) are generally unregulated and that the Commission relied on the underlying futures market as the regulated market of significant size that formed the basis for approving the series of Currency [16]                                          and Commodity-Based Trust Shares, including gold, silver, platinum, palladium, copper, and other commodities and currencies. The Commission specifically noted in the Winklevoss Order that the First Gold Approval Order “was based on an assumption that the currency market and the spot gold market were largely unregulated.” [17] 

As such, the regulated market of significant size test does not require that the spot bitcoin market be regulated in order for the Commission to approve this proposal, and precedent makes clear that an underlying market for a spot commodity or currency being a regulated market would actually be an exception to the norm. These largely unregulated currency and commodity markets do not provide the same protections as the markets that are subject to the Commission's oversight, but the Commission has consistently looked to surveillance sharing agreements with the underlying futures market in order to determine whether such products were consistent with the Act. With this in mind, the Chicago Mercantile Exchange (“CME”) bitcoin futures (“Bitcoin Futures”) market is the proper market to consider in determining whether there is a related regulated market of significant size.

                    Further to this point, the Exchange notes that the Commission has approved proposals related to the listing and trading of funds that would primarily hold CME Bitcoin Futures that are registered under the Securities Act of 1933.[18]                                          In the Teucrium Approval, the Commission found the CME Bitcoin Futures market to be a regulated market of significant size as it relates to CME Bitcoin Futures, an odd tautological truth that is also inconsistent with prior disapproval orders for ETPs that would hold actual bitcoin instead of derivatives contracts (“Spot Bitcoin ETPs”) that use the exact same pricing methodology as the CME Bitcoin Futures. As further discussed below, both the Exchange and the Sponsor believe that this proposal and the included analysis are sufficient to establish that the CME Bitcoin Futures market represents a regulated market of significant size as it relates both to the CME Bitcoin Futures market and to the spot bitcoin market and that this proposal should be approved.                

Finally, as discussed in greater detail below, the Trust provides investors interested in exposure to bitcoin with important protections that are not always available to investors that invest directly in bitcoin, including protection against insolvency, cyber attacks, and other risks. If U.S. investors had access to vehicles such as the Trust for their bitcoin investments, instead of directing their bitcoin investments into loosely regulated offshore vehicles (such as loosely regulated centralized trading platforms that have since faced bankruptcy proceedings or other insolvencies), then countless investors would have protected their principal investments in bitcoin and thus benefited.

#### Background

                    Bitcoin is a digital asset based on the decentralized, open-source protocol of the peer-to-peer computer network launched in 2009 that governs the creation, movement, and ownership of bitcoin and hosts the public ledger, or “blockchain,” on which all bitcoin transactions are recorded (the “Bitcoin Network” or “Bitcoin”). The decentralized nature of the Bitcoin Network allows parties to transact directly with one another based on cryptographic proof instead of relying on a trusted third party. The protocol also lays out the rate of issuance of new bitcoin within the Bitcoin Network, a rate that is reduced by half approximately every four years with an eventual hard cap of 21 million. It's generally understood that the combination of these two features—a systemic hard cap of 21 million bitcoin and the ability to transact trustlessly with anyone connected to the Bitcoin Network—gives bitcoin its value.[19]                                          The                           ( print page 2390)                        first rule filing proposing to list an ETP to provide exposure to bitcoin in the U.S. was submitted by the Exchange on June 30, 2016.[20]                                          At that time, blockchain technology, and digital assets that utilized it, were relatively new to the broader public. The market cap of all bitcoin in existence at that time was approximately $10 billion. No registered offering of digital asset securities or shares in an investment vehicle with exposure to bitcoin or any other cryptocurrency had yet been conducted, and the regulated infrastructure for conducting a digital asset securities offering had not begun to develop.[21]                                          Similarly, regulated U.S. Bitcoin Futures contracts did not exist. The CFTC had determined that bitcoin is a commodity,[22]                                          but had not engaged in significant enforcement actions in the space. The New York Department of Financial Services (“NYDFS”) adopted its final “BitLicense” regulatory framework in 2015, but had only approved four entities to engage in activities relating to virtual currencies (whether through granting a BitLicense or a limited-purpose trust charter) as of June 30, 2016.[23]                                          While the first over-the-counter bitcoin fund launched in 2013, public trading was limited and the fund had only $60 million in assets.[24]                                          There were very few, if any, traditional financial institutions engaged in the space, whether through investment or providing services to digital asset companies. In January 2018, the staff of the Commission noted in a letter to the Investment Company Institute (“ICI”) and Securities Industry and Financial Markets Association (“SIFMA”) that it was not aware, at that time, of a single custodian providing fund custodial services for digital assets.[25]                                          Fast forward to today and the digital assets financial ecosystem, including bitcoin, has progressed significantly. The development of a regulated market for digital asset securities has significantly evolved, with market participants having conducted registered public offerings of both digital asset securities [26]                                          and shares in investment vehicles holding Bitcoin Futures.[27]                                          Additionally, licensed and regulated service providers have emerged to provide fund custodial services for digital assets, among other services. For example, in February 2023, the Commission proposed to amend Rule 206(4)-2 under the Advisers Act of 1940 (the “custody rule”) to expand the scope beyond client funds and securities to include all crypto assets, among other assets; [28]                                          in May 2021, the staff of the Commission released a statement permitting open-end mutual funds to invest in cash-settled Bitcoin Futures; in December 2020, the Commission adopted a conditional no-action position permitting certain special purpose broker-dealers to custody digital asset securities under Rule 15c3-3 under the Exchange Act (the “Custody Statement”); [29]                                          in September 2020, the staff of the Commission released a no-action letter permitting certain broker-dealers to operate a non-custodial Alternative Trading System (“ATS”) for digital asset securities, subject to specified conditions; [30]                                          in October 2019, the staff of the Commission granted temporary relief from the clearing agency registration requirement to an entity seeking to establish a securities clearance and settlement system based on distributed ledger technology,[31]                                          and multiple transfer agents who provide services for digital asset securities registered with the Commission.[32] 

                    Outside the Commission's purview, the regulatory landscape has changed significantly since 2016, and cryptocurrency markets have grown and evolved as well. The market for bitcoin is approximately 100 times larger, having at one point reached a market cap of over $1 trillion.[33]                                          According to the CME Bitcoin Futures report, from February 13, 2023 through March 27, 2023, CFTC regulated Bitcoin Futures represented between $750 million and $3.2 billion in notional trading volume on CME Bitcoin Futures on a daily basis.[34]                                          Open interest was over $1.4 billion for the entirety of the period and at one point was over $2 billion. The CFTC has exercised its regulatory jurisdiction in bringing a number of enforcement actions related to bitcoin and against trading platforms that offer cryptocurrency trading.[35]                                          As of                           ( print page 2391)                        February 14, 2023 the NYDFS has granted no fewer than thirty-four BitLicenses,[36]                                          including to established public payment companies like PayPal Holdings, Inc. and Square, Inc., and limited purpose trust charters to entities providing cryptocurrency custody services, including the Trust's Custodian.[37]                                          In addition, the Treasury's Office of Foreign Assets Control (“OFAC”) has brought enforcement actions over apparent violations of the sanctions laws in connection with the provision of wallet management services for digital assets.[38] 

                    In addition to the regulatory developments laid out above, more traditional financial market participants have become more active in cryptocurrency: large insurance companies, asset managers, university endowments, pension funds, and even historically bitcoin skeptical fund managers have allocated to bitcoin. As noted in the Financial Stability Oversight Council (“FSOC”) report on Digital Asset Financial Stability Risks and Regulation, “[i]ndustry surveys suggest that the scale of these investments grew quickly during the boom in crypto-asset markets through late 2021. In June 2022, PwC estimated that the number of crypto-specialist hedge funds was more than 300 globally, with $4.1 billion in assets under management. In addition, in a survey PwC found that 38 percent of surveyed traditional hedge funds were currently investing in `digital assets,' compared to 21 percent the year prior.” [39]                                          The largest over-the-counter bitcoin fund previously filed a Form 10 registration statement, which the staff of the Commission reviewed and which took effect automatically, and is now a reporting company.[40]                                          Established companies like Tesla, Inc., MicroStrategy Incorporated, and Square, Inc., among others, announced substantial investments in bitcoin in amounts as large as $1.5 billion (Tesla) and $425 million (MicroStrategy). The foregoing examples demonstrate that bitcoin has gained mainstream usage and recognition.                

                    Despite these developments, access for U.S. retail investors to gain exposure to bitcoin via a transparent and U.S. regulated, U.S. exchange-traded vehicle remains limited. Instead current options include: (i) facing the counter-party risk, legal uncertainty, technical risk, and complexity associated with accessing spot bitcoin; (ii) over-the-counter bitcoin funds (“OTC Bitcoin Funds”) with high management fees and potentially volatile premiums and discounts; [41]                                          (iii) purchasing shares of operating companies that they believe will provide proxy exposure to bitcoin with limited disclosure about the associated risks; [42]                                          or (iv) purchasing Bitcoin Futures exchange-traded funds (“ETFs”), as defined below, which represent a sub-optimal structure for long-term investors that will cost them significant amounts of money every year compared to Spot Bitcoin ETPs, as further discussed below. Meanwhile, investors in many other countries, including Canada and Brazil, are able to use more traditional exchange listed and traded products (including ETFs holding physical bitcoin) to gain exposure to bitcoin. Similarly, investors in Switzerland and across Europe have access to ETPs (issued by 21Shares, among others) which trade on regulated exchanges and provide exposure to a broad array of spot crypto assets. U.S. investors, by contrast, are left with fewer and more risky means of getting bitcoin exposure, as described above.[43] 

                    To this point, the lack of a Spot Bitcoin ETP exposes U.S. investor assets to significant risk because investors that would otherwise seek crypto asset exposure through a Spot Bitcoin ETP are forced to find alternative exposure through generally riskier means. For instance, many U.S. investors that held their digital assets in accounts at FTX,[44]                                          Celsius Network LLC,[45]                                          BlockFi Inc.[46]                                          and Voyager Digital Holdings, Inc.[47]                                          have become unsecured creditors in the insolvencies of those entities. If a Spot Bitcoin ETP was available, it is likely that at least a portion of the billions of dollars tied up in those proceedings would still reside in the brokerage accounts of U.S. investors, having instead been invested in a transparent, regulated, and well-understood structure—a Spot Bitcoin ETP. To this point, approval of a Spot Bitcoin ETP would represent a major win for the protection of U.S. investors in the crypto asset space. As further described below, the Trust, like all other series of Commodity-Based Trust Shares, is designed to protect investors against the                           ( print page 2392)                        risk of losses through fraud and insolvency that arise by holding digital assets, including bitcoin, on centralized platforms.                

Additionally, investors in other countries, specifically Canada, generally pay lower fees than U.S. retail investors that invest in OTC Bitcoin Funds due to the fee pressure that results from increased competition among available bitcoin investment options. Without an approved and regulated Spot Bitcoin ETP in the U.S. as a viable alternative, U.S. investors could seek to purchase shares of non-U.S. bitcoin vehicles in order to get access to bitcoin exposure. Given the separate regulatory regime and the potential difficulties associated with any international litigation, such an arrangement would create more risk exposure for U.S. investors than they would otherwise have with a U.S. exchange listed ETP. In addition to the benefits to U.S. investors articulated throughout this proposal, approving this proposal (and others like it) would provide U.S. ETFs and mutual funds with a U.S.-listed and regulated product to provide such access rather than relying on either flawed products or products listed and primarily regulated in other countries.

#### Bitcoin Futures ETFs

The Exchange and Sponsor applaud the Commission for allowing the launch of ETFs registered under the Investment Company Act of 1940, as amended (the “1940 Act”) and the Bitcoin Futures Approvals that provide exposure to bitcoin primarily through CME Bitcoin Futures (“Bitcoin Futures ETFs”). Allowing such products to list and trade is a productive first step in providing U.S. investors and traders with transparent, exchange-listed tools for expressing a view on bitcoin. The Bitcoin Futures Approvals, however, have created a logical inconsistency in the application of the standard the Commission applies when considering Bitcoin ETP proposals.

                    As discussed further below, the standard applicable to Bitcoin ETPs is whether the listing exchange has in place a comprehensive surveillance sharing agreement with a regulated market of significant size in the underlying asset. Previous disapproval orders have made clear that a market that constitutes a regulated market of significant size is generally a futures and/or options market based on the underlying reference asset rather than the spot commodity markets, which are often unregulated.[48]                                          Leaving aside the analysis of that standard until later in this proposal,[49]                                          the Exchange believes that the following rationale the Commission applied to a Bitcoin Futures ETF should result in the Commission approving this and other Spot Bitcoin ETP proposals:                

                        The CME “comprehensively surveils futures market conditions and price movements on a real-time and ongoing basis in order to detect and prevent price distortions, including price distortions caused by manipulative efforts.” Thus, the CME's surveillance can reasonably be relied upon to capture the effects on the CME bitcoin futures market caused by a person attempting to manipulate the proposed futures ETP by manipulating the price of CME bitcoin futures contracts, whether that attempt is made by directly trading on the CME bitcoin futures market or indirectly by trading outside of the CME bitcoin futures market. As such, when the CME shares its surveillance information with Arca, the information would assist in detecting and deterring fraudulent or manipulative misconduct related to the non-cash assets held by the proposed ETP.[50] 

                    CME Bitcoin Futures pricing is based on pricing from spot bitcoin markets. The statement from the Teucrium Approval that “CME's surveillance can reasonably be relied upon to capture the effects on the CME Bitcoin Futures market caused by a person attempting to manipulate the proposed futures ETP by manipulating the price of CME Bitcoin Futures contracts . . . indirectly by trading outside of the CME Bitcoin Futures market,” makes clear that the Commission believes that CME's surveillance can capture the effects of trading on the relevant spot markets on the pricing of CME Bitcoin Futures. This was further acknowledged in the “Grayscale lawsuit” [51]                                          when Judge Rao stated “. . . the Commission in the Teucrium order recognizes that the futures prices are influenced by the spot prices, and the Commission concludes in approving futures ETPs that any fraud on the spot market can be adequately addressed by the fact that the futures market is a regulated one . . .” The Exchange agrees with the Commission on this point and notes that the pricing mechanism applicable to the Shares is similar to that of the CME Bitcoin Futures. As further discussed below, this view is also consistent with the Sponsor's research.                

                    The structure of Bitcoin Futures ETFs provides negative outcomes for buy and hold investors as compared to a Spot Bitcoin ETP.[52]                                          Specifically, the cost of rolling CME Bitcoin Futures contracts will cause the Bitcoin Futures ETFs to lag the performance of bitcoin itself and, at over a billion dollars in assets under management, would cost U.S. investors significant amounts of money on an annual basis compared to Spot Bitcoin ETPs. Such rolling costs would not be required for Spot Bitcoin ETPs that hold bitcoin. Further, Bitcoin Futures ETFs could potentially hit CME position limits, which would force a Bitcoin Futures ETF to invest in non-futures assets for bitcoin exposure and cause potential investor confusion and lack of certainty about what such Bitcoin Futures ETFs are actually holding to try to get exposure to bitcoin, not to mention completely changing the risk profile associated with such an ETF. While Bitcoin Futures ETFs represent a useful trading tool, they are clearly a sub-optimal structure for U.S. investors that are looking for long-term exposure to bitcoin that will, based on the calculations above, unnecessarily cost U.S. investors significant amounts of money every year compared to Spot Bitcoin ETPs and the Exchange believes that any proposal to list and trade a Spot Bitcoin ETP should be reviewed by the Commission with this important investor protection context in mind.                

                    To the extent the Commission may view differential treatment of Bitcoin Futures ETFs and Spot Bitcoin ETPs as                           ( print page 2393)                        warranted based on the Commission's concerns about the custody of physical bitcoin that a Spot Bitcoin ETP would hold (compared to cash-settled futures contracts),[53]                                          the Sponsor believes this concern is mitigated to a significant degree by the custodial arrangements that the Trust has contracted with the Custodian to provide, as further outlined below. In the Custody Statement, the Commission stated that the fourth step that a broker-dealer could take to shield traditional securities customers and others from the risks and consequences of digital asset security fraud, theft, or loss is to establish, maintain, and enforce reasonably designed written policies, procedures, and controls for safekeeping and demonstrating the broker-dealer has exclusive possession or control over digital asset securities that are consistent with industry best practices to protect against the theft, loss, and unauthorized and accidental use of the private keys necessary to access and transfer the digital asset securities the broker-dealer holds in custody. While bitcoin is not a security and the Custodian is not a broker-dealer, the Sponsor believes that similar considerations apply to the Custodian's holding of the Trust's bitcoin. After diligent investigation, the Sponsor believes that the Custodian's policies, procedures, and controls for safekeeping, exclusively possessing, and controlling the Trust's bitcoin holdings are consistent with industry best practices to protect against the theft, loss, and unauthorized and accidental use of the private keys. As a trust company chartered by the NYDFS, the Sponsor notes that the Custodian is subject to extensive regulation and has among longest track records in the industry of providing custodial services for digital asset private keys. Under the circumstances, therefore, to the extent the Commission believes that its concerns about the risks of spot bitcoin custody justifies differential treatment of a Bitcoin Futures ETF versus a Spot Bitcoin ETP, the Sponsor believes that the fact that the Custodian employs the same types of policies, procedures, and safeguards in handling spot bitcoin that the Commission has stated that broker-dealers should implement with respect to digital asset securities would appear to weaken the justification for treating a Bitcoin Futures ETF compared to a Spot Bitcoin ETP differently due to spot bitcoin custody concerns.                

Based on the foregoing, the Exchange and Sponsor believe that any objective review of the proposals to list Spot Bitcoin ETPs compared to the Bitcoin Futures ETFs and the Bitcoin Futures Approvals would lead to the conclusion that Spot Bitcoin ETPs should be available to U.S. investors and, as such, this proposal and other comparable proposals to list and trade Spot Bitcoin ETPs should be approved by the Commission. Stated simply, U.S. investors will continue to lose significant amounts of money from holding Bitcoin Futures ETFs as compared to Spot Bitcoin ETPs, losses which could be prevented by the Commission approving Spot Bitcoin ETPs. Additionally, any concerns related to preventing fraudulent and manipulative acts and practices related to Spot Bitcoin ETPs would apply equally to the spot markets underlying the futures contracts held by a Bitcoin Futures ETF. Both the Exchange and Sponsor believe that the CME Bitcoin Futures market is a regulated market of significant size and that such manipulation concerns are mitigated, as described extensively below. After allowing and approving the listing and trading of Bitcoin Futures ETFs that hold primarily CME Bitcoin Futures, however, the only consistent outcome would be approving Spot Bitcoin ETPs on the basis that the CME Bitcoin Futures market is a regulated market of significant size.

Given the current landscape, approving this proposal (and others like it) and allowing Spot Bitcoin ETPs to be listed and traded alongside Bitcoin Futures ETFs would establish a consistent regulatory approach, provide U.S. investors with choice in product structures for bitcoin exposure, and offer flexibility in the means of gaining exposure to bitcoin through transparent, regulated, U.S. exchange-listed vehicles.

####                     Bitcoin Futures [54] 

                    CME began offering trading in Bitcoin Futures in 2017. Each contract represents five bitcoin and is based on the CME CF Bitcoin Reference Rate.[55]                                          The contracts trade and settle like other cash-settled commodity futures contracts. Nearly every measurable metric related to Bitcoin Futures has trended consistently up since launch.                

                    According to the Sponsor, the increase in the volume on CME, over the past few years, is reflected in a higher proportion of the bitcoin market share. This is illustrated by plotting the proportion of monthly volume traded in bitcoin on the CME [56]                                          (categorized as regulated in the chart and used as the numerator) in relation to the total bitcoin market, which is comprised of the sum of the volume of Bitcoin Futures on the CME and the spot volume on cryptocurrency trading platforms [57]                                          (categorized as unregulated and used as the denominator) from January 1, 2018 to January 31, 2023.                
      ( print page 2394)    
The proportion of volume traded on CME has increased from less than 1% at inception, to more than 10% over three and a half years. Furthermore, the CME market, as well as other crypto-linked markets, and the spot market are highly correlated. In markets that are globally and efficiently integrated, one would expect that changes in prices of an asset across all markets to be highly correlated. The rationale behind this is that quick and efficient arbitrageurs would capture potentially profitable opportunities, consequently converging prices to the average intrinsic value very rapidly.

                    Bitcoin markets exhibit a high degree of correlation. Using daily bitcoin prices from centralized trading platforms, ETP providers, and the CME from January 20, 2021 to February 1, 2023,[58]                                          the Sponsor calculates the Pearson correlation of returns [59]                                          across these markets and find a high degree of correlation.                

Correlations are between 57% and 99%, with the latter found mainly across centralized trading platforms due to their higher level of interconnectedness. The lower correlations pertain mainly to the ETPs, which are relatively newer products and are mainly offered by a few competing market makers who are required to trade in large blocks, thus making it economically infeasible to capture small mispricings. As additional investors and arbitrageurs enter the market and capture the mispricing opportunities between these markets, it is likely that there will be much higher levels of correlations across all markets.
      ( print page 2395)    
Pair-wise correlations of bitcoin returns are also calculated on hourly and minute-by-minute sampling frequencies in order to estimate the intra-day associations across the different bitcoin markets. The results show correlations no less than 92% among centralized trading platforms and between the CME Bitcoin Futures and centralized trading platforms on an hourly basis, and no less than 78% on a minutely basis. This suggests that bitcoin prices on centralized trading platforms and the CME markets move very similarly and in a very efficient manner to quickly reflect changes in market conditions, not only on a daily basis, but also at much higher intra-day frequencies.
      ( print page 2396)          ( print page 2397)    
                    According to the Sponsor's research, this relationship holds true during periods of extreme price volatility. This implies that no single bitcoin market can deviate significantly from the consensus, such that the market is sufficiently large and has an inherent unique resistance to manipulation. Hence, the Sponsor introduces a statistical co-moment called co-kurtosis, which measures to what extent two random variables change together.[60]                                          If two returns series exhibit a high degree of co-kurtosis, this means that they tend to undergo extreme positive and negative changes simultaneously. A co-kurtosis value larger than +3 or less than −3 is considered statistically significant. The following table shows that the level of co-kurtosis is positive and very high between all market combinations of hourly returns, which suggests that bitcoin markets tend to move very similarly especially for extreme price deviations.                

#### Co-Kurtosis of Bitcoin Hourly Returns Across Centralized Exchanges, ETPs, and the CME

      ( print page 2398)    
As a robustness check, the co-kurtosis metric is also calculated using minute-by-minute returns, and the conclusion remains the same, suggesting that all bitcoin markets move in tandem especially during extreme market movements.

#### Co-Kurtosis of Bitcoin Minutely Returns Across Centralized Exchanges, ETPs, and the CME

These results present evidence of a robust global bitcoin market that quickly reacts in a unanimous manner to extreme price movements across both the spot markets, futures and ETP markets.

                    The Sponsor further believes that academic research corroborates the overall trend outlined above and supports the thesis that the Bitcoin Futures pricing leads the spot market and, thus, a person attempting to manipulate the Shares would also have to trade on that market to manipulate the ETP. Specifically, the Sponsor believes that such research indicates                           ( print page 2399)                        that Bitcoin Futures lead the bitcoin spot market in price formation.[61] 

#### Section 6(b)(5) and the Applicable Standards

                    The Commission has approved numerous series of Trust Issued Receipts,[62]                                          including Commodity-Based Trust Shares,[63]                                          to be listed on U.S. national securities exchanges. In order for any proposed rule change from an exchange to be approved, the Commission must determine that, among other things, the proposal is consistent with the requirements of section 6(b)(5) of the Act, specifically including: (i) the requirement that a national securities exchange's rules are designed to prevent fraudulent and manipulative acts and practices; [64]                                          and (ii) the requirement that an exchange proposal be designed, in general, to protect investors and the public interest. The Exchange believes that this proposal is consistent with the requirements of section 6(b)(5) of the Act and that this filing sufficiently demonstrates that the CME Bitcoin Futures market represents a regulated market of significant size and that, on the whole, the manipulation concerns previously articulated by the Commission are sufficiently mitigated to the point that they are outweighed by quantifiable investor protection issues that would be resolved by approving this proposal.                

#### (i) Designed To Prevent Fraudulent and Manipulative Acts and Practices

                    In order to meet this standard in a proposal to list and trade a series of Commodity-Based Trust Shares, the Commission requires that an exchange demonstrate that there is a comprehensive surveillance-sharing agreement in place [65]                                          with a regulated market of significant size. Both the Exchange and CME are members of the Intermarket Surveillance Group (“ISG”).[66]                                          The only remaining issue to be addressed is whether the Bitcoin Futures market constitutes a market of significant size, which both the Exchange and the Sponsor believe that it does. The terms “significant market” and “market of significant size” include a market (or group of markets) as to which: (a) there is a reasonable likelihood that a person attempting to manipulate the ETP would also have to trade on that market to manipulate the ETP, so that a surveillance-sharing agreement would assist the listing exchange in detecting and deterring misconduct; and (b) it is unlikely that trading in the ETP would be the predominant influence on prices in that market.[67] 

                    The Commission has also recognized that the “regulated market of significant size” standard is not the only means for satisfying section 6(b)(5) of the act, specifically providing that a listing exchange could demonstrate that “other means to prevent fraudulent and manipulative acts and practices” are sufficient to justify dispensing with the requisite surveillance-sharing agreement.[68] 

#### (a) Manipulation of the ETP

                    According to the Sponsor's research presented above, the Bitcoin Futures market is the leading market for bitcoin price formation. Where Bitcoin Futures lead the price in the spot market such that a potential manipulator of the bitcoin spot market (beyond just the constituents of the Index [69]                                         ) would have to participate in the Bitcoin Futures market, it follows that a potential manipulator of the Shares would similarly have to transact in the Bitcoin Futures market because the Index is based on spot prices. As such, the Exchange believes that part (a) of the significant market test outlined above is satisfied and that common membership in ISG between the Exchange and CME would assist the listing exchange in detecting and deterring misconduct in the Shares.                

#### (b) Predominant Influence on Prices in Spot and Bitcoin Futures

                    The Exchange and Sponsor also believe that trading in the Shares would not be the predominant force on prices                           ( print page 2400)                        in the Bitcoin Futures market or spot market for a number of reasons, including the significant volume in the Bitcoin Futures market, the size of bitcoin's market cap, and the significant liquidity available in the spot market. In addition to the Bitcoin Futures market data points cited above, the spot market for bitcoin is also very liquid.                

#### (c) Other Means To Prevent Fraudulent and Manipulative Acts and Practices

As noted above, the Commission also permits a listing exchange to demonstrate that “other means to prevent fraudulent and manipulative acts and practices” are sufficient to justify dispensing with the requisite surveillance-sharing agreement. The Exchange and Sponsor believe that such conditions are present.

                    According to the Sponsor, a significant portion of the considerations around crypto pricing have historically stemmed from a lack of consistent pricing across markets. However, according to the Sponsor's research, cross-platforms spreads in bitcoin have been declining consistently over the past several years. Based on the daily bitcoin price series from several popular centralized trading platforms [70]                                          the Sponsor has calculated the largest cross-platform percentage spread (labelled as %C-Spread) by deducting the highest or maximum price (P) at time t from the lowest or minimum, and dividing by the lowest across all trading platforms (i). Formally, this is expressed as:                

The results show a clear and sharp decline in the %C-Spread, indicating that the bitcoin market has become more efficient as cross-platform prices have converged over time.

In addition, the magnitude of outlier % C-spreads has also declined over time. This boxplot shows that, not only did the median value of the %C-Spread decline over time, but also the extreme outlier values. For instance, the maximum %C-Spread for 2017, 2018, 2019, 2020, 2021, 2022, and 2023 (up until February 01, 2023) are 29.14%, 14.12%, 8.54%, 6.04%, 3.65%, 5.56%, and 0.63%, respectively. The market has experienced a 38% year-on-year decline in the annual median %C-Spread indicating a greater degree of bitcoin price convergence across trading platforms and a more efficient market.
      ( print page 2401)    
The dispersion (σ) of bitcoin Prices has also declined over the same period. This chart shows the 7-day rolling standard deviation of the %C-Spread from January 1, 2017 to February 1, 2023. The Sponsor's research finds that the dispersion in bitcoin prices across all trading platforms has decreased over time, indicating that prices on all the considered trading platforms converge towards the intrinsic average much more efficiently. This suggests that the market has become better at quickly reaching a consensus price for bitcoin.

As the pricing of the crypto market becomes increasingly efficient, pricing methodologies become more accurate and less susceptible to manipulation. The clustering of prices across a variety of sources within the primary market points towards robust price discovery mechanisms and efficient arbitrage.
      ( print page 2402)    
One factor that has contributed to the overall efficiency of, and improved price discovery within the bitcoin market is the increase in the number of participants, and subsequently, the total dollar amount allocated to this market. This can be illustrated by the following chart, which shows the number of wallet addresses holding bitcoin from January 2016 to February 2023.

The large number of participants in the bitcoin market has manifested itself in high liquidity in the market. This is exhibited in the following chart, which shows the daily aggregated dollar notional of the bid and ask order books within the first 100 price levels across several of the largest centralized crypto trading platforms from February 2022 to January 2023. Specifically, the dollar notional that is allocated closest to the mid price has hovered between $2.6 million and $12 million over that period.
      ( print page 2403)    
An increased notional order book suggests that there is a higher degree of consensus among investors regarding the price of bitcoin. Moreover, this market characteristic hampers any attempt of price manipulation by any single large entity.

As a robustness check, the Sponsor investigates whether the dollar notional in the order book changes significantly prior to and post an extreme price event. Specifically, for events constituting large increases in the price of bitcoin, if the ask (or sell) side of the order book experiences a significant shrinkage in the dollar notional right before the event, then this may be an indication of market manipulation whereby the ask-side of the order book becomes sufficiently thin for a large order to move the price upward. Similarly, for events constituting large decreases in the price of bitcoin, if the bid (or buy) side of the order book experiences a significant shrinkage in the dollar notional prior to such events, then this may be an indication of market manipulation whereby the thinner bid-side of the order book may potentially lead to significant downward price movements.

Using the top and bottom 0.1% of hourly price changes from February 1, 2022 to February 1, 2023 as events of extreme upward and downward market movements, respectively, the Sponsor plotted the bid (left charts) and ask (right charts) dollar notional of the bitcoin order book within a six-hour window around these events in the chart below, which shows the results for extreme upward price movements. The extreme price events (indicated by the dashed green lines) perfectly coincide with the decrease in dollar notional of the ask-side of the order book. This is indicative of an efficient market, whereby large market movements are quickly and dynamically absorbed by a thick orderbook. Moreover, the dollar notional on the ask side after the event is replenished back to its pre-event level, which implies that market participants' reactions are quick to restore the market back to its equilibrium level.
      ( print page 2404)    
The same results and conclusions are found for extreme downward price movements. The charts below show that such price events perfectly coincide with shrinkages on the bid side of the order book (left charts), indicating an efficient and dynamic bitcoin market. Moreover, the bid-side of the order book after the event is also restored back to its pre-event level, which suggests that the market is symmetrically efficient in moving back to equilibrium.
      ( print page 2405)    

#### (ii) Designed To Protect Investors and the Public Interest

The Exchange believes that the proposal is designed to protect investors and the public interest. Over the past several years, U.S. investor exposure to bitcoin through OTC Bitcoin Funds has grown into the tens of billions of dollars, including through Bitcoin Futures ETFs. With that growth, so too has grown the quantifiable investor protection issues to U.S. investors through roll costs for Bitcoin Futures ETFs and premium/discount volatility and management fees for OTC Bitcoin Funds. The Exchange believes that the concerns related to the prevention of fraudulent and manipulative acts and practices have been sufficiently addressed to be consistent with the Act and, to the extent that the Commission disagrees with that assertion, such concerns are now outweighed by investor protection concerns. As such, the Exchange believes that approving this proposal (and comparable proposals) provides the Commission with the opportunity to allow U.S. investors with access to bitcoin in a regulated and transparent exchange-traded vehicle that would act to limit risk to U.S. investors by: (i) reducing premium and discount volatility; (ii) reducing management fees through meaningful competition; (iii) reducing risks and costs associated with investing in Bitcoin Futures ETFs and operating companies that are imperfect proxies for bitcoin exposure; and (iv) providing an alternative to custodying spot bitcoin.

#### ARK 21Shares Bitcoin ETF

                    Delaware Trust Company is the trustee (“Trustee”). The Bank of New York Mellon will be the administrator (“Administrator”) and transfer agent (“Transfer Agent”). Foreside Global Services, LLC will be the marketing agent (“Marketing Agent”) in connection with the creation and redemption of “Baskets” of Shares. ARK Investment Management LLC (the                           ( print page 2406)                        “Subadviser”) [71]                                          is the sub-adviser of the Trust and will provide data, research, and, as needed, operational support to the Trust, including with respect to assistance in the marketing of the Shares. As noted above, Coinbase Custody Trust Company, LLC, is the Custodian and will be responsible for custody of the Trust's bitcoin. The Bank of New York Mellon (the “Cash Custodian”) will act as custodian of the Trust's cash and cash equivalents.                

                    According to the Registration Statement, each Share will represent a fractional undivided beneficial interest in the Trust. The Trust's assets will only consist of bitcoin, cash, and cash equivalents.[72] 

                    According to the Registration Statement, the Trust is neither an investment company registered under the Investment Company Act of 1940, as amended,[73]                                          nor a commodity pool for purposes of the Commodity Exchange Act (“CEA”), and neither the Trust nor the Sponsor is subject to regulation as a commodity pool operator or a commodity trading adviser in connection with the Shares.                

When the Trust creates or redeems its Shares, it will do so in cash transactions in blocks of 5,000 Shares (a “Creation Basket”) at the Trust's net asset value (“NAV”). Authorized participants will deliver, or facilitate the delivery of, cash to the Trust's account with the Cash Custodian, in exchange for Shares when they create Shares, and the Trust, through the Cash Custodian, will deliver cash to such authorized participants when they redeem Shares with the Trust. Authorized participants may then offer Shares to the public at prices that depend on various factors, including the supply and demand for Shares, the value of the Trust's assets, and market conditions at the time of a transaction.

As noted above, the Trust is designed to protect investors against the risk of losses through fraud and insolvency that arise by holding bitcoin on centralized platforms. Specifically, the Trust is designed to protect investors as follows:

#### (i) Assets of the Trust Protected From Insolvency

                    The Trust's bitcoin will be held by its Custodian,[74]                                          which is a New York chartered trust company overseen by the NYDFS and a qualified custodian under Rule 206-4 of the Investment Adviser Act. The Custodian will custody the Trust's bitcoin pursuant to a custody agreement, which requires the Custodian to maintain the Trust's bitcoin in segregated accounts that clearly identify the Trust as owner of the accounts and assets held on those accounts; the segregation will be both from the proprietary property of the Custodian and the assets of any other customer. Such an arrangement is generally deemed to be “bankruptcy remote,” that is, in the event of an insolvency of the Custodian, assets held in such segregated accounts would not become property of the Custodian's estate and would not be available to satisfy claims of creditors of the Custodian. In addition, according to the Registration Statement, the Custodian carries fidelity insurance, which covers assets held by the Custodian in custody from risks such as theft of funds. These arrangements provide significant protections to investors and could have mitigated the type of losses incurred by investors in the numerous crypto-related insolvencies, including Celsius, Voyager, BlockFi and FTX.                

#### (ii) Trust's Transfer Agent Will Instruct Disposition of Trust's Bitcoin

                    According to the Registration Statement, except with respect to sale of bitcoin from time to time to cover expenses of the Trust, the only time bitcoin will move into or out from the Trust will be with respect to creations or redemptions of Shares of the Trust. In such cases, a third party will use cash to buy and deliver bitcoin to create Shares or withdraw and sell bitcoin for cash to redeem Shares, on behalf of the Trust. Authorized participants will deliver cash to the Trust's account with the Cash Custodian in exchange for Shares of the Trust, and the Trust, through the Cash Custodian, will deliver cash to authorized participants when those authorized participants redeem Shares of the Trust. The Transfer Agent will facilitate the settlement of Shares in response to the placement of creation orders and redemption orders from authorized participants. The creation and redemption procedures are administered by the Transfer Agent, an independent third party. Specifically, Shares are issued in registered form in accordance with the Trust agreement.[75]                                          The Transfer Agent has been appointed registrar and transfer agent for the purpose of transferring Shares in certificated form. The Transfer Agent keeps a record of all shareholders and holder of the Shares in certified form in the registry. The Sponsor recognizes transfers of Shares in certified form only if done in accordance with the Trust agreement. In other words, according to the Registration Statement, with very limited exceptions, the Sponsor will not give instructions with respect to the transfer or disposition of the Trust's bitcoin. Bitcoin owned by the Trust will at all times be held by, and in the control of, the Custodian, and transfer of such bitcoin to or from the Custodian will occur only in connection with creation and redemptions of Shares. This will provide safeguards against the movement of bitcoin owned by the Trust by or to the Sponsor or affiliates of the Sponsor.                

#### (iii) Trust's Assets Are Subject to Regular Audit

According to the Registration Statement, audit trails exist for all movement of bitcoin within Custodian-controlled bitcoin wallets and are audited annually for accuracy and completeness by an independent external audit firm. In addition, the Trust will be audited by an independent registered public accounting firm on a regular basis.

#### (iv) Trust is Subject to the Exchange's Obligations of Companies Listed on the Exchange and Applicable Corporate Governance Requirements

                    The Trust will be subject to the obligations of companies listed on the Exchange set forth in BZX Rule 14.6, which require the listed companies to make public disclosure of material events and any notifications of deficiency by the Exchange, file and distribute period financial reports,                           ( print page 2407)                        engage independent public accountants registered with the Exchange, among other things. Such disclosures serve a key investor protection role. In addition, the Trust will be subject to the corporate governance requirements for companies listed on the Exchange set forth in BZX Rule 14.10.                

#### Investment Objective

According to the Registration Statement and as further described below, the investment objective of the Trust is to seek to track the performance of bitcoin, as measured by the performance of the CME CF Bitcoin Reference Rate—New York Variant (the “Index”), adjusted for the Trust's expenses and other liabilities. In seeking to achieve its investment objective, the Trust will hold bitcoin and will value the Shares daily based on the Index. The Trust will process all creations and redemptions in cash transactions with authorized participants. The Trust is not actively managed.

#### The Index

As described in the Registration Statement, the Trust will use the Index to calculate the Trust's NAV. The Trust will determine the bitcoin Index price and value its Shares daily based on the value of bitcoin as reflected by the Index. The Index is calculated daily and aggregates the notional value of bitcoin trading activity across major bitcoin spot trading platforms. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate (“BRR”), including utilizing the same constituent bitcoin trading platforms, which is the underlying rate to determine settlement of CME Bitcoin Futures contracts, except that the Index is calculated as of 4 p.m. ET, whereas the BRR is calculated as of 4 p.m. London time. The Index is designed based on the International Organization of Securities Commissions (“IOSCO”) Principals for Financial Benchmarks. The administrator of the Index is CF Benchmarks Ltd. (the “Index Provider”). The Trust also uses the bitcoin Index price to calculate its bitcoin holdings, which is the aggregate U.S. Dollar value of bitcoins in the Trust, based on the bitcoin Index price, less its liabilities and expenses.

The Index was created to facilitate financial products based on bitcoin. It serves as a once-a-day benchmark rate of the U.S. dollar price of bitcoin (USD/BTC), calculated as of 4 p.m. ET. The Index, which has been calculated and published since February 28, 2022, aggregates the trade flow of several bitcoin trading platforms, during an observation window between 3:00 p.m. and 4:00 p.m. ET into the U.S. dollar price of one bitcoin at 4:00 p.m. ET. Specifically, the Index is calculated based on the “Relevant Transactions” (as defined below) of all of its constituent bitcoin trading platforms, which are currently Coinbase, Bitstamp, Kraken, itBit, LMAX Digital and Gemini (the “Constituent Platforms”), as follows:
    - All Relevant Transactions are added to a joint list, recording the time of execution, trade price and size for each transaction.
    - The list is partitioned by timestamp into 12 equally-sized time intervals of 5 (five) minute length.
    - For each partition separately, the volume-weighted median trade price is calculated from the trade prices and sizes of all Relevant Transactions, i.e.,                      across all Constituent Platforms. A volume-weighted median differs from a standard median in that a weighting factor, in this case trade size, is factored into the calculation.                
    - The Index is then determined by the equally-weighted average of the volume medians of all partitions.

#### Description of the Index, Index Construction and Maintenance

The Index does not include any futures prices in its methodology. A “Relevant Transaction” is any cryptocurrency versus U.S. dollar spot trade that occurs during the observation window between 3:00 p.m. and 4:00 p.m. ET on a Constituent Platform in the BTC/USD pair that is reported and disseminated by a Constituent Platform through its publicly available Application Programming Interface (“API”) and observed by the Index Provider.

An oversight function is implemented by the Index Provider in seeking to ensure that the Index is administered through the Index Provider's codified policies for Index integrity, which include a conflicts of interest policy, a control framework, an accountability framework, and an input data policy. The Index is subject to oversight by the CME CF Oversight Committee. The CME CF Oversight Committee shall be comprised of at least five members, including at least: (i) two who are representatives of CME (“CME Members”); (ii) one who is a representative of CF (“CF Member”); and (iii) two who bring expertise and industry knowledge relating to benchmark determination, issuance and operations. The CME CF Oversight Committee meets no less frequently than quarterly. The CME CF Oversight Committee's Founding Charter and quarterly meeting minutes are publicly available.

The Sponsor believes that the use of the Index is reflective of a reasonable valuation of the average spot price of bitcoin and that resistance to manipulation is a priority aim of its design methodology. The methodology: (i) takes an observation period and divides it into equal partitions of time; (ii) then calculates the volume-weighted median of all transactions within each partition; and (iii) the value is determined from the arithmetic mean of the volume-weighted medians, equally weighted. By employing the foregoing steps, the Index thereby seeks to ensure that transactions in bitcoin conducted at outlying prices do not have an undue effect on the value of a specific partition, large trades or clusters of trades transacted over a short period of time will not have an undue influence on the index level, and the effect of large trades at prices that deviate from the prevailing price are mitigated from having an undue influence on the benchmark level.

                    Index data and the description of the Index are based on information made publicly available by the Index Provider on its website at                     *https://www.cfbenchmarks.com.*

#### Net Asset Value

NAV means the total assets of the Trust (which includes all bitcoin and cash and cash equivalents) less total liabilities of the Trust. The Administrator determines the NAV of the Trust on each day that the Exchange is open for regular trading, as promptly as practical after 4:00 p.m. EST. The NAV of the Trust is the aggregate value of the Trust's assets less its estimated accrued but unpaid liabilities (which include accrued expenses). In determining the Trust's NAV, the Administrator values the bitcoin held by the Trust based on the price set by the Index as of 4:00 p.m. EST. The Administrator also determines the NAV per Share.

The NAV for the Trust will be calculated by the Administrator once a day and will be disseminated daily to all market participants at the same time.

                    If the Index is not available, or if the Sponsor determines in good faith that the Index does not reflect an accurate bitcoin price, then the Administrator will employ an alternative method to determine the fair value of the Trust's assets.[76]

#### Availability of Information

                    In addition to the price transparency of the Index, the Trust will provide information regarding the Trust's bitcoin holdings as well as additional data regarding the Trust. The website for the Trust, which will be publicly accessible at no charge, will contain the following information: (a) the current NAV per Share daily and the prior business day's NAV and the reported closing price; (b) the BZX Official Closing Price [77]                                          in relation to the NAV as of the time the NAV is calculated and a calculation of the premium or discount of such price against such NAV; (c) data in chart form displaying the frequency distribution of discounts and premiums of the Official Closing Price against the NAV, within appropriate ranges for each of the four previous calendar quarters (or for the life of the Trust, if shorter); (d) the prospectus; and (e) other applicable quantitative information. The aforementioned information will be published as of the close of business and available on the Sponsor's website at                     *www.21shares.com,*                     or any successor thereto.                

The Intraday Indicative Value (“IIV”) will be calculated by using the prior day's closing NAV per Share as a base and updating that value during Regular Trading Hours to reflect changes in the value of the Trust's bitcoin holdings during the trading day. The IIV disseminated during Regular Trading Hours should not be viewed as an actual real-time update of the NAV, which will be calculated only once at the end of each trading day. The IIV may differ from the NAV due to the differences in the time window of trades used to calculate each price (the NAV uses the Index price as of 4 p.m. ET, whereas the IIV draws prices from the last trade on each Constituent Platform in an effort to produce a relevant, real-time price). The Trust will provide an IIV per Share updated every 15 seconds, as calculated by the Exchange or a third-party financial data provider during the Exchange's Regular Trading Hours (9:30 a.m. to 4:00 p.m. E.T.). The IIV will be widely disseminated on a per Share basis every 15 seconds during the Exchange's Regular Trading Hours through the facilities of the consolidated tape association (CTA) and Consolidated Quotation System (CQS) high speed lines. In addition, the IIV will be available through on-line information services such as Bloomberg and Reuters.

The price of bitcoin will be made available by one or more major market data vendors, updated at least every 15 seconds during Regular Trading Hours.

                    As noted above, the Index is calculated daily and aggregates the notional value of bitcoin trading activity across major bitcoin spot trading platforms. Index data, value, and the description of the Index are based on information made publicly available by the Index Provider on its website at                     *https://www.cfbenchmarks.com.*

Quotation and last sale information for bitcoin is widely disseminated through a variety of major market data vendors, including Bloomberg and Reuters. Information relating to trading, including price and volume information, in bitcoin is available from major market data vendors and from the trading platforms on which bitcoin are traded. Depth of book information is also available from bitcoin trading platforms. The normal trading hours for bitcoin trading platforms are 24 hours per day, 365 days per year.

Information regarding market price and trading volume of the Shares will be continually available on a real-time basis throughout the day on brokers' computer screens and other electronic services. Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the Consolidated Tape Association (“CTA”).

#### The Bitcoin Custodian

The Custodian carefully considers the design of the physical, operational and cryptographic systems for secure storage of the Trust's private keys in an effort to lower the risk of loss or theft. The Custodian utilizes a variety of security measures to ensure that private keys necessary to transfer digital assets remain uncompromised and that the Trust maintains exclusive ownership of its assets. The operational procedures of the Custodian are reviewed by third-party advisors with specific expertise in physical security. The devices that store the keys will never be connected to the internet or any other public or private distributed network—this is colloquially known as “cold storage.” Only specific individuals are authorized to participate in the custody process, and no individual acting alone will be able to access or use any of the private keys. In addition, no combination of the executive officers of the Sponsor or the investment professionals managing the Trust, acting alone or together, will be able to access or use any of the private keys that hold the Trust's bitcoin.

#### Creation and Redemption of Shares

                    When the Trust creates or redeems its Shares, it will do so in cash transactions in blocks of 5,000 Shares that are based on the quantity of bitcoin attributable to each Share of the Trust (                    *e.g.,*                     a Creation Basket) at the Trust's NAV. The authorized participants will deliver only cash to create shares and will receive only cash when redeeming shares. Further, authorized participants will not directly or indirectly purchase, hold, deliver, or receive bitcoin as part of the creation or redemption process or otherwise direct the Trust or a third party with respect to purchasing, holding, delivering, or receiving bitcoin as part of the creation or redemption process. The Trust will create shares by receiving bitcoin from a third party that is not the authorized participant and the Trust—not the authorized participant—is responsible for selecting the third party to deliver the bitcoin. Further, the third party will not be acting as an agent of the authorized participant with respect to the delivery of the bitcoin to the Trust or acting at the direction of the authorized participant with respect to the delivery of the bitcoin to the Trust. The Trust will redeem shares by delivering bitcoin to a third party that is not the authorized participant and the Trust—not the authorized participant—is responsible for selecting the third party to receive the bitcoin. Further, the third party will not be acting as an agent of the authorized participant with respect to the receipt of the bitcoin from the Trust or acting at the direction of the authorized participant with respect to the receipt of the bitcoin from the Trust.                

                    According to the Registration Statement, on any business day, an authorized participant may place an order to create one or more Creation Basket. Purchase orders must be placed by 12:00 p.m. Eastern Time, the close of regular trading on the Exchange, or another time determined by the Sponsor. The day on which an order is received is considered the purchase order date. The total deposit of cash required is an amount of cash sufficient to purchase such amount of bitcoin, the amount of which is equal to the combined NAV of the number of Shares included in the Creation Baskets being created determined as promptly as practicable after 4:00 p.m. ET on the date the order to purchase is properly received. The Administrator determines the quantity of bitcoin used to calculate the cash deposit in the Creation Basket                           ( print page 2409)                        for a given day by dividing the number of bitcoin held by the Trust as of the opening of business on that business day, adjusted for the amount of bitcoin constituting estimated accrued but unpaid fees and expenses of the Trust as of the opening of business on that business day, by the quotient of the number of Shares outstanding at the opening of business divided by 5,000. For example, assume the total bitcoin held by the Trust less any estimated accrued but unpaid fees and expenses is 1,000 bitcoin and the total number of Shares outstanding is 10,000. The Administrator would determine the required deposit as follows:                

Total deposited cash as described in the example above would be 500 multiplied by the purchase price of bitcoin.

The procedures by which an authorized participant can redeem one or more Creation Baskets mirror the procedures for the creation of Creation Baskets. A third party, that is unaffiliated with the Trust and the Sponsor, will use cash to buy and deliver bitcoin to create Shares or withdraw and sell bitcoin for cash to redeem Shares, on behalf of the Trust.

The Sponsor will maintain ownership and control of bitcoin in a manner consistent with good delivery requirements for spot commodity transactions.

#### Rule 14.11(e)(4)—Commodity-Based Trust Shares

                    The Shares will be subject to BZX Rule 14.11(e)(4), which sets forth the initial and continued listing criteria applicable to Commodity-Based Trust Shares. The Exchange represents that, for initial and continued listing, the Trust must be in compliance with Rule 10A-3 under the Act. A minimum of 10,000 Shares will be outstanding at the commencement of listing on the Exchange. The Exchange will obtain a representation that the NAV will be calculated daily and information about the NAV and the assets of the Trust will be made available to all market participants at the same time. The Exchange notes that, as defined in Rule 14.11(e)(4)(C)(i), the Shares will be: (a) issued by a trust that holds (1) a specified commodity [78]                                          deposited with the trust, or (2) a specified commodity and, in addition to such specified commodity, cash; (b) issued by such trust in a specified aggregate minimum number in return for a deposit of a quantity of the underlying commodity and/or cash; and (c) when aggregated in the same specified minimum number, may be redeemed at a holder's request by such trust which will deliver to the redeeming holder the quantity of the underlying commodity and/or cash.                

                    Upon termination of the Trust, the Shares will be removed from listing. The Trustee, Delaware Trust Company, is a trust company having substantial capital and surplus and the experience and facilities for handling corporate trust business, as required under Rule 14.11(e)(4)(E)(iv)(a) and that no change will be made to the trustee without prior notice to and approval of the Exchange. The Exchange also notes that, pursuant to Rule 14.11(e)(4)(F), neither the Exchange nor any agent of the Exchange shall have any liability for damages, claims, losses or expenses caused by any errors, omissions or delays in calculating or disseminating any underlying commodity value, the current value of the underlying commodity required to be deposited to the Trust in connection with issuance of Commodity-Based Trust Shares; resulting from any negligent act or omission by the Exchange, or any agent of the Exchange, or any act, condition or cause beyond the reasonable control of the Exchange, its agent, including, but not limited to, an act of God; fire; flood; extraordinary weather conditions; war; insurrection; riot; strike; accident; action of government; communications or power failure; equipment or software malfunction; or any error, omission or delay in the reports of transactions in an underlying commodity. Finally, as required in Rule 14.11(e)(4)(G), the Exchange notes that any registered market maker (“Market Maker”) in the Shares must file with the Exchange in a manner prescribed by the Exchange and keep current a list identifying all accounts for trading in an underlying commodity, related commodity futures or options on commodity futures, or any other related commodity derivatives, which the registered Market Maker may have or over which it may exercise investment discretion. No registered Market Maker shall trade in an underlying commodity, related commodity futures or options on commodity futures, or any other related commodity derivatives, in an account in which a registered Market Maker, directly or indirectly, controls trading activities, or has a direct interest in the profits or losses thereof, which has not been reported to the Exchange as required by this Rule. In addition to the existing obligations under Exchange rules regarding the production of books and records (see,                     *e.g.,*                     Rule 4.2), the registered Market Maker in Commodity-Based Trust Shares shall make available to the Exchange such books, records or other information pertaining to transactions by such entity or registered or non-registered employee affiliated with such entity for its or their own accounts for trading the underlying physical commodity, related commodity futures or options on commodity futures, or any other related commodity derivatives, as may be requested by the Exchange.                

The Exchange is able to obtain information regarding trading in the Shares and the underlying bitcoin, Bitcoin Futures contracts, options on Bitcoin Futures, or any other bitcoin derivative through members acting as registered Market Makers, in connection with their proprietary or customer trades.

As a general matter, the Exchange has regulatory jurisdiction over its members, and their associated persons. The Exchange also has regulatory jurisdiction over any person or entity controlling a member, as well as a subsidiary or affiliate of a member that is in the securities business. A subsidiary or affiliate of a member organization that does business only in commodities would not be subject to Exchange jurisdiction, but the Exchange could obtain information regarding the activities of such subsidiary or affiliate through surveillance sharing agreements with regulatory organizations of which such subsidiary or affiliate is a member.

#### Trading Halts

                    With respect to trading halts, the Exchange may consider all relevant                           ( print page 2410)                        factors in exercising its discretion to halt or suspend trading in the Shares. The Exchange will halt trading in the Shares under the conditions specified in BZX Rule 11.18. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable. These may include: (1) the extent to which trading is not occurring in the bitcoin underlying the Shares; or (2) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. Trading in the Shares also will be subject to Rule 14.11(e)(4)(E)(ii), which sets forth circumstances under which trading in the Shares may be halted.                

If the IIV or the value of the Index is not being disseminated as required, the Exchange may halt trading during the day in which the interruption to the dissemination of the IIV or the value of the Index occurs. If the interruption to the dissemination of the IIV or the value of the Index persists past the trading day in which it occurred, the Exchange will halt trading no later than the beginning of the trading day following the interruption.

In addition, if the Exchange becomes aware that the NAV with respect to the Shares is not disseminated to all market participants at the same time, it will halt trading in the Shares until such time as the NAV is available to all market participants.

#### Trading Rules

The Exchange deems the Shares to be equity securities, thus rendering trading in the Shares subject to the Exchange's existing rules governing the trading of equity securities. BZX will allow trading in the Shares during all trading sessions on the Exchange. The Exchange has appropriate rules to facilitate transactions in the Shares during all trading sessions. As provided in BZX Rule 11.11(a), the minimum price variation for quoting and entry of orders in securities traded on the Exchange is $0.01 where the price is greater than $1.00 per share or $0.0001 where the price is less than $1.00 per share. The Shares of the Trust will conform to the initial and continued listing criteria set forth in BZX Rule 14.11(e)(4).

#### Surveillance

The Exchange represents that its surveillance procedures are adequate to properly monitor the trading of the Shares on the Exchange during all trading sessions and to deter and detect violations of Exchange rules and the applicable federal securities laws. Trading of the Shares through the Exchange will be subject to the Exchange's surveillance procedures for derivative products, including Commodity-Based Trust Shares. FINRA conducts certain cross-market surveillances on behalf of the Exchange pursuant to a regulatory services agreement. The Exchange is responsible for FINRA's performance under this regulatory services agreement.

                    The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares and Bitcoin Futures with other markets and other entities that are members of the ISG, and the Exchange, or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares and Bitcoin Futures from such markets and other entities.[79]                                          The Exchange may obtain information regarding trading in the Shares and Bitcoin Futures via ISG, from other exchanges who are members or affiliates of the ISG, or with which the Exchange has entered into a comprehensive surveillance sharing agreement.                

In addition, the Exchange also has a general policy prohibiting the distribution of material, non-public information by its employees.

The issuer has represented to the Exchange that it will advise the Exchange of any failure by the Trust or the Shares to comply with the continued listing requirements, and, pursuant to its obligations under section 19(g)(1) of the Exchange Act, the Exchange will surveil for compliance with the continued listing requirements. If the Trust or the Shares are not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under Exchange Rule 14.12.

#### Information Circular

                    Prior to the commencement of trading, the Exchange will inform its members in an Information Circular of the special characteristics and risks associated with trading the Shares. Specifically, the Information Circular will discuss the following: (i) the procedures for the creation and redemption of Baskets (and that the Shares are not individually redeemable); (ii) BZX Rule 3.7, which imposes suitability obligations on Exchange members with respect to recommending transactions in the Shares to customers; (iii) how information regarding the IIV and the Trust's NAV are disseminated; (iv) the risks involved in trading the Shares outside of Regular Trading Hours [80]                                          when an updated IIV will not be calculated or publicly disseminated; (v) the requirement that members deliver a prospectus to investors purchasing newly issued Shares prior to or concurrently with the confirmation of a transaction; and (vi) trading information. The Information Circular will also reference the fact that there is no regulated source of last sale information regarding bitcoin, that the Commission has no jurisdiction over the trading of bitcoin as a commodity, and that the CFTC has regulatory jurisdiction over the trading of Bitcoin Futures contracts and options on Bitcoin Futures contracts.                

In addition, the Information Circular will advise members, prior to the commencement of trading, of the prospectus delivery requirements applicable to the Shares. Members purchasing the Shares for resale to investors will deliver a prospectus to such investors. The Information Circular will also discuss any exemptive, no-action and interpretive relief granted by the Commission from any rules under the Act.

#### 2. Statutory Basis

                    The Exchange believes that the proposal is consistent with section 6(b) of the Act [81]                                          in general and section 6(b)(5) of the Act [82]                                          in particular in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system and, in general, to protect investors and the public interest.                

                    The Commission has approved numerous series of Trust Issued Receipts,[83]                                          including Commodity-Based Trust Shares,[84]                                          to be listed on U.S. national securities exchanges. In order for any proposed rule change from an exchange to be approved, the Commission must determine that, among other things, the proposal is consistent with the requirements of section 6(b)(5) of the Act, specifically including: (i) the requirement that a national securities exchange's rules are designed to prevent fraudulent and                           ( print page 2411)                        manipulative acts and practices; [85]                                          and (ii) the requirement that an exchange proposal be designed, in general, to protect investors and the public interest. The Exchange believes that this proposal is consistent with the requirements of section 6(b)(5) of the Act and that this filing sufficiently demonstrates that the CME Bitcoin Futures market represents a regulated market of significant size and that, on the whole, the manipulation concerns previously articulated by the Commission are sufficiently mitigated to the point that they are outweighed by quantifiable investor protection issues that would be resolved by approving this proposal.                

#### (i) Designed To Prevent Fraudulent and Manipulative Acts and Practices

                    In order to meet this standard in a proposal to list and trade a series of Commodity-Based Trust Shares, the Commission requires that an exchange demonstrate that there is a comprehensive surveillance-sharing agreement in place [86]                                          with a regulated market of significant size. Both the Exchange and CME are members of ISG.[87]                                          The only remaining issue to be addressed is whether the Bitcoin Futures market constitutes a market of significant size, which both the Exchange and the Sponsor believe that it does. The terms “significant market” and “market of significant size” include a market (or group of markets) as to which: (a) there is a reasonable likelihood that a person attempting to manipulate the ETP would also have to trade on that market to manipulate the ETP, so that a surveillance-sharing agreement would assist the listing exchange in detecting and deterring misconduct; and (b) it is unlikely that trading in the ETP would be the predominant influence on prices in that market.[88] 

                    The Commission has also recognized that the “regulated market of significant size” standard is not the only means for satisfying section 6(b)(5) of the act, specifically providing that a listing exchange could demonstrate that “other means to prevent fraudulent and manipulative acts and practices” are sufficient to justify dispensing with the requisite surveillance-sharing agreement.[89] 

#### (a) Manipulation of the ETP

                    According to the Sponsor's research presented above, the Bitcoin Futures market is the leading market for bitcoin price formation. Where Bitcoin Futures lead the price in the spot market such that a potential manipulator of the bitcoin spot market (beyond just the constituents of the Index [90]                                         ) would have to participate in the Bitcoin Futures market, it follows that a potential manipulator of the Shares would similarly have to transact in the Bitcoin Futures market because the Index is based on spot prices. As such, the Exchange believes that part (a) of the significant market test outlined above is satisfied and that common membership in ISG between the Exchange and CME would assist the listing exchange in detecting and deterring misconduct in the Shares.                

#### (b) Predominant Influence on Prices in Spot and Bitcoin Futures

The Exchange and Sponsor also believe that trading in the Shares would not be the predominant force on prices in the Bitcoin Futures market or spot market for a number of reasons, including the significant volume in the Bitcoin Futures market, the size of bitcoin's market cap, and the significant liquidity available in the spot market. In addition to the Bitcoin Futures market data points cited above, the spot market for bitcoin is also very liquid.

#### (c) Other Means To Prevent Fraudulent and Manipulative Acts and Practices

As noted above, the Commission also permits a listing exchange to demonstrate that “other means to prevent fraudulent and manipulative acts and practices” are sufficient to justify dispensing with the requisite surveillance-sharing agreement. The Exchange and Sponsor believe that such conditions are present.

                    The Exchange believes that the proposal is designed to protect investors and the public interest. Over the past several years, U.S. investor exposure to bitcoin through OTC Bitcoin Funds has grown into the tens of billions of dollars and more than a billion dollars of exposure through Bitcoin Futures ETFs. With that growth, so too has grown the quantifiable investor protection issues to U.S. investors through roll costs for Bitcoin Futures ETFs and premium/discount volatility and management fees for OTC Bitcoin Funds. The Exchange                           ( print page 2412)                        believes that the concerns related to the prevention of fraudulent and manipulative acts and practices have been sufficiently addressed to be consistent with the Act and, to the extent that the Commission disagrees with that assertion, also believes that such concerns are now outweighed by these investor protection concerns. As such, the Exchange believes that approving this proposal (and comparable proposals) provides the Commission with the opportunity to allow U.S. investors with access to bitcoin in a regulated and transparent exchange-traded vehicle that would act to limit risk to U.S. investors by: (i) reducing premium and discount volatility; (ii) reducing management fees through meaningful competition; (iii) reducing risks and costs associated with investing in Bitcoin Futures ETFs and operating companies that are imperfect proxies for bitcoin exposure; and (iv) providing an alternative to custodying spot bitcoin.                

#### Commodity-Based Trust Shares

The Exchange believes that the proposed rule change is designed to prevent fraudulent and manipulative acts and practices in that the Shares will be listed on the Exchange pursuant to the initial and continued listing criteria in Exchange Rule 14.11(e)(4). The Exchange believes that its surveillance procedures are adequate to properly monitor the trading of the Shares on the Exchange during all trading sessions and to deter and detect violations of Exchange rules and the applicable federal securities laws. Trading of the Shares through the Exchange will be subject to the Exchange's surveillance procedures for derivative products, including Commodity-Based Trust Shares. The issuer has represented to the Exchange that it will advise the Exchange of any failure by the Trust or the Shares to comply with the continued listing requirements, and, pursuant to its obligations under section 19(g)(1) of the Exchange Act, the Exchange will surveil for compliance with the continued listing requirements. If the Trust or the Shares are not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under Exchange Rule 14.12. The Exchange may obtain information regarding trading in the Shares and listed bitcoin derivatives via the ISG, from other exchanges who are members or affiliates of the ISG, or with which the Exchange has entered into a comprehensive surveillance sharing agreement.

#### Availability of Information

                    The Exchange also believes that the proposal promotes market transparency in that a large amount of information is currently available about bitcoin and will be available regarding the Trust and the Shares. In addition to the price transparency of the Index, the Trust will provide information regarding the Trust's bitcoin holdings as well as additional data regarding the Trust. The website for the Trust, which will be publicly accessible at no charge, will contain the following information: (a) the current NAV per Share daily and the prior business day's NAV and the reported closing price; (b) the BZX Official Closing Price [91]                                          in relation to the NAV as of the time the NAV is calculated and a calculation of the premium or discount of such price against such NAV; (c) data in chart form displaying the frequency distribution of discounts and premiums of the Official Closing Price against the NAV, within appropriate ranges for each of the four previous calendar quarters (or for the life of the Trust, if shorter); (d) the prospectus; and (e) other applicable quantitative information. The aforementioned information will be published as of the close of business and available on the Sponsor's website at                     *www.21shares.com,*                     or any successor thereto.                

The Trust will provide an IIV per Share updated every 15 seconds, as calculated by the Exchange or a third-party financial data provider during the Exchange's Regular Trading Hours (9:30 a.m. to 4:00 p.m. E.T.). The IIV will be widely disseminated on a per Share basis every 15 seconds during the Exchange's Regular Trading Hours through the facilities of the consolidated tape association (CTA) and Consolidated Quotation System (CQS) high speed lines. In addition, the IIV will be available through on-line information services such as Bloomberg and Reuters.

The price of bitcoin will be made available by one or more major market data vendors, updated at least every 15 seconds during Regular Trading Hours.

                    As noted above, the Index is calculated daily and aggregates the notional value of bitcoin trading activity across major bitcoin spot trading platforms. Index data, value, and the description of the Index are based on information made publicly available by the Index Provider on its website at                     *https://www.cfbenchmarks.com.*

Quotation and last sale information for bitcoin is widely disseminated through a variety of major market data vendors, including Bloomberg and Reuters. Information relating to trading, including price and volume information, in bitcoin is available from major market data vendors and from the trading platforms on which bitcoin are traded. Depth of book information is also available from bitcoin trading platforms. The normal trading hours for bitcoin trading platforms are 24 hours per day, 365 days per year.

Information regarding market price and trading volume of the Shares will be continually available on a real-time basis throughout the day on brokers' computer screens and other electronic services. Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the Consolidated Tape Association (“CTA”).

In sum, the Exchange believes that this proposal is consistent with the requirements of section 6(b)(5) of the Act, that this filing sufficiently demonstrates that the CME Bitcoin Futures market represents a regulated market of significant size, and that on the whole the manipulation concerns previously articulated by the Commission are sufficiently mitigated to the point that they are outweighed by investor protection issues that would be resolved by approving this proposal.

                    The Exchange believes that the proposal is, in particular, designed to protect investors and the public interest. The investor protection issues for U.S. investors has grown significantly over the last several years, through roll costs for Bitcoin Futures ETFs and premium/discount volatility and management fees for OTC Bitcoin Funds. As discussed throughout, this growth investor protection concerns need to be re-evaluated and rebalanced with the prevention of fraudulent and manipulative acts and practices concerns that previous disapproval orders have relied upon. Finally, the Exchange notes that in addition to all of the arguments herein which it believes sufficiently establish the CME Bitcoin Futures market as a regulated market of significant size, it is logically inconsistent to find that the CME Bitcoin Futures market is a significant market as it relates to the CME Bitcoin Futures market, but not a significant market as it relates to the bitcoin spot market for the numerous reasons laid out above.                          ( print page 2413)    

For the above reasons, the Exchange believes that the proposed rule change is consistent with the requirements of section 6(b)(5) of the Act.

### B. Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purpose of the Act. The Exchange notes that the proposed rule change, rather will facilitate the listing and trading of an additional exchange-traded product that will enhance competition among both market participants and listing venues, to the benefit of investors and the marketplace.

### C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

The Exchange has neither solicited nor received written comments on the proposed rule change.

41.                             The premium and discount for OTC Bitcoin Funds is known to move rapidly. For example, over the period of 12/21/20 to 1/21/21, the premium for the largest OTC Bitcoin Fund went from 40.18% to 2.79%. While the price of bitcoin appreciated significantly during this period and NAV per share increased by 41.25%, the price per share increased by only 3.58%. This means that investors are buying shares of a fund that experiences significant volatility in its premium and discount outside of the fluctuations in price of the underlying asset. Even operating within the normal premium and discount range, it's possible for an investor to buy shares of an OTC Bitcoin Fund only to have those shares quickly lose 10% or more in dollar value excluding any movement of the price of bitcoin. That is to say—the price of bitcoin could have stayed exactly the same from market close on one day to market open the next, yet the value of the shares held by the investor decreased only because of the fluctuation of the premium. As more investment vehicles, including mutual funds and ETFs, seek to gain exposure to bitcoin, the easiest option for a buy and hold strategy for such vehicles is often an OTC Bitcoin Fund, meaning that even investors that do not directly buy OTC Bitcoin Funds can be disadvantaged by extreme premiums (or discounts) and premium volatility.

42.                             A number of operating companies engaged in unrelated businesses—such as Tesla (a car manufacturer) and MicroStrategy (an enterprise software company)—have announced investments as large as $5.3 billion in bitcoin. Without access to bitcoin exchange-traded products, retail investors seeking investment exposure to bitcoin may end up purchasing shares in these companies in order to gain the exposure to bitcoin that they seek. In fact, mainstream financial news networks have written a number of articles providing investors with guidance for obtaining bitcoin exposure through publicly traded companies (such as MicroStrategy, Tesla, and bitcoin mining companies, among others) instead of dealing with the complications associated with buying spot bitcoin in the absence of a bitcoin ETP.                         *See e.g.,*                         “7 public companies with exposure to bitcoin” (February 8, 2021) available at:                         *https://finance.yahoo.com/​news/​7-public-companies-with-exposure-to-bitcoin-154201525.html;*                         and “Want to get in the crypto trade without holding bitcoin yourself?

59.                             The Pearson correlation is a measure of linear association between two variables and indicates the magnitude as well as direction of this relationship. The value can range between −1 (suggesting a strong negative association) and 1 (suggesting a strong positive association).

60.                             Co-skewness and Co-kurtosis are higher order cross-moments used in finance to examine how assets move together. Co-skewness measures the extent to which two variables undergo extreme deviations at the same time, whereby a positive (negative) value means that both values exhibit positive (negative) values simultaneously. While this measure is useful for estimating co-movements in one direction or the other, it does not allow us to test whether two variables comove similarly in either direction. For that, we apply the co-kurtosis, which measures the extent to which two variables undergo both extreme positive and negative deviations at the same time.

Causality, cointegration and price discovery from a time-varying perspective” (available at:                         *https://www.ncbi.nlm.nih.gov/​pmc/​articles/​PMC7481826/​*). This academic research paper concludes that “There exist no episodes where the Bitcoin spot markets dominates the price discovery processes with regard to Bitcoin futures. This points to a conclusion that the price formation originates solely in the Bitcoin futures market. We can, therefore, conclude that the Bitcoin futures markets dominate the dynamic price discovery process based upon time-varying information share measures. Overall, price discovery seems to occur in the Bitcoin futures markets rather than the underlying spot market based upon a time-varying perspective.”                         *See also*                         Matthew Hougan, Hong Kim, and Satyajeet Pal (2021). “Price Discovery in the Modern Bitcoin Market: Examining Lead-Lag Relationships Between the Bitcoin Spot and Bitcoin Futures Market” (available at                         *https://static.bitwiseinvestments.com/​Bitwise-Bitcoin-ETP-White-Paper-1.pdf*). This academic research paper also concluded that “the CME bitcoin futures market is the dominant source of price discovery when compared with the bitcoin spot market, and that prices on the CME bitcoin futures market lead prices on bitcoin spot markets . . .”

64.                             As the Exchange has stated in a number of other public documents, it continues to believe that bitcoin is resistant to price manipulation and that “other means to prevent fraudulent and manipulative acts and practices” exist to justify dispensing with the requisite surveillance sharing agreement. The geographically diverse and continuous nature of bitcoin trading render it difficult and prohibitively costly to manipulate the price of bitcoin. The fragmentation across bitcoin platforms, the relatively slow speed of transactions, and the capital necessary to maintain a significant presence on each trading platform make manipulation of bitcoin prices through continuous trading activity challenging. To the extent that there are bitcoin trading platforms engaged in or allowing wash trading or other activity intended to manipulate the price of bitcoin on other markets, such pricing does not normally impact prices on other trading platforms because participants will generally ignore markets with quotes that they deem non-executable. Moreover, the linkage between the bitcoin markets and the presence of arbitrageurs in those markets means that the manipulation of the price of bitcoin price on any single venue would require manipulation of the global bitcoin price in order to be effective. Arbitrageurs must have funds distributed across multiple trading platforms in order to take advantage of temporary price dislocations, thereby making it unlikely that there will be strong concentration of funds on any particular bitcoin trading platform or OTC platform. As a result, the potential for manipulation on a trading platform would require overcoming the liquidity supply of such arbitrageurs who are effectively eliminating any cross-market pricing differences.

65.                             As previously articulated by the Commission, “The standard requires such surveillance-sharing agreements since “they provide a necessary deterrent to manipulation because they facilitate the availability of information needed to fully investigate a manipulation if it were to occur.” The Commission has emphasized that it is essential for an exchange listing a derivative securities product to enter into a surveillance-sharing agreement with markets trading underlying securities for the listing exchange to have the ability to obtain information necessary to detect, investigate, and deter fraud and market manipulation, as well as violations of exchange rules and applicable federal securities laws and rules. The hallmarks of a surveillance-sharing agreement are that the agreement provides for the sharing of information about market trading activity, clearing activity, and customer identity; that the parties to the agreement have reasonable ability to obtain access to and produce requested information; and that no existing rules, laws, or practices would impede one party to the agreement from obtaining this information from, or producing it to, the other party.” The Commission has historically held that joint membership in the Intermarket Surveillance Group constitutes such a surveillance sharing agreement.

71.                             The Subadviser is an investment adviser. An investment adviser to an open-end fund is required to be registered under the Investment Advisers Act of 1940 (the “Advisers Act”). As a result, the Adviser and its related personnel are subject to the provisions of Rule 204A-1 under the Advisers Act relating to codes of ethics. This Rule requires investment advisers to adopt a code of ethics that reflects the fiduciary nature of the relationship to clients as well as compliance with other applicable securities laws. Accordingly, procedures designed to prevent the communication and misuse of non-public information by an investment adviser must be consistent with Rule 204A-1 under the Advisers Act. In addition, Rule 206(4)-7 under the Advisers Act makes it unlawful for an investment adviser to provide investment advice to clients unless such investment adviser has (i) adopted and implemented written policies and procedures reasonably designed to prevent violation, by the investment adviser and its supervised persons, of the Advisers Act and the Commission rules adopted thereunder; (ii) implemented, at a minimum, an annual review regarding the adequacy of the policies and procedures established pursuant to subparagraph (i) above and the effectiveness of their implementation; and (iii) designated an individual (who is a supervised person) responsible for administering the policies and procedures adopted under subparagraph (i) above.

To the extent that there are bitcoin trading platforms engaged in or allowing wash trading or other activity intended to manipulate the price of bitcoin on other markets, such activity does not normally impact prices on other trading platforms because participants will generally ignore markets with quotes that they deem non-executable. The reason is that wash trading aims to manipulate the volume rather than the price of an asset to give the impression of heightened market activity in hopes of attracting investors to that asset. Moreover, wash trades are executed within a trading platform rather than cross trading platforms since the entity executing the wash trades would aim to trade against itself, and as such, this can only happen within a trading platform. Should the wash trades of that entity result in a deviation of the price on that trading platform relative to others, arbitrageurs would then be able to capitalize on this mispricing, and bring the manipulated price back to equilibrium, resulting in a loss to the entity executing the wash trades. Moreover, the linkage between the bitcoin markets and the presence of arbitrageurs in those markets means that the manipulation of the price of bitcoin price on any single venue would require manipulation of the global bitcoin price in order to be effective.
