## 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

                    The Exchange proposes to list and trade the Shares under BZX Rule 14.11(e)(4),[4]                                          which governs the listing and trading of Commodity-Based Trust Shares on the Exchange.[5]                                          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”).[6] 

#### 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.[7]                                          The first rule filing proposing to list an exchange-traded product to provide exposure to bitcoin in the U.S. was submitted by the Exchange on June 30, 2016.[8]                                          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.[9]                                          Similarly, regulated U.S. bitcoin futures contracts did not exist. The Commodity Futures Trading Commission (the “CFTC”) had determined that bitcoin is a commodity,[10]                                          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.[11]                                          While the first over-the-counter bitcoin fund launched in 2013, public trading was limited and the fund had only $60 million in assets.[12]                                          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 and SIFMA that it was not aware, at that time, of a single custodian providing fund custodial services for digital assets.[13]                                          Fast forward to the first quarter of 2021 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 [14]                                          and shares in investment                           ( print page 43291)                        vehicles holding bitcoin futures.[15]                                          Additionally, licensed and regulated service providers have emerged to provide fund custodial services for digital assets, among other services. For example, 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; [16]                                          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; [17]                                          and 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,[18]                                          and multiple transfer agents who provide services for digital asset securities registered with the Commission.[19] 

                    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 recently reached a market cap of over $1 trillion, although as of June 18, 2021, it is closer to $650 billion. CFTC regulated bitcoin futures represented approximately $28 billion in notional trading volume on Chicago Mercantile Exchange (“CME”) (“Bitcoin Futures”) in December 2020 compared to $737 million, $1.4 billion, and $3.9 billion in total trading in December 2017, December 2018, and December 2019, respectively. Bitcoin Futures traded over $1.2 billion per day in December 2020 and represented $1.6 billion in open interest compared to $115 million in December 2019, which the Exchange believes represents a regulated market of significant size, as further discussed below.[20]                                          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.[21]                                          The U.S. Office of the Comptroller of the Currency (the “OCC”) has made clear that federally-chartered banks are able to provide custody services for cryptocurrencies and other digital assets.[22]                                          The OCC recently granted conditional approval of two charter conversions by state-chartered trust companies to national banks, both of which provide cryptocurrency custody services.[23]                                          NYDFS has granted no fewer than twenty-five BitLicenses, 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. The U.S. Treasury Financial Crimes Enforcement Network (“FinCEN”) has released extensive guidance regarding the applicability of the Bank Secrecy Act (“BSA”) and implementing regulations to virtual currency businesses,[24]                                          and has proposed rules imposing requirements on entities subject to the BSA that are specific to the technological context of virtual currencies.[25]                                          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.[26] 

                    In addition to the regulatory developments laid out above, more traditional financial market participants appear to be embracing cryptocurrency: large insurance companies,[27]                                          asset managers,[28]                                          university endowments,[29]                                          pension funds,[30]                                          and even historically bitcoin skeptical fund managers [31]                                          are allocating to bitcoin. The largest over-the-counter bitcoin fund previously                           ( print page 43292)                        filed a Form 10 registration statement, which the Staff of the Commission reviewed and which took effect automatically, and is now a reporting company.[32]                                          Established companies like Tesla, Inc.,[33]                                          MicroStrategy Incorporated,[34]                                          and Square, Inc.,[35]                                          among others, have recently announced substantial investments in bitcoin in amounts as large as $1.5 billion (Tesla) and $425 million (MicroStrategy). Suffice to say, bitcoin is on its way to gaining mainstream usage.                

                    Despite these developments, access for U.S. retail investors to gain exposure to bitcoin via a transparent and regulated exchange-traded vehicle remains limited. As investors and advisors increasingly utilize ETPs to manage diversified portfolios (including equities, fixed income securities, commodities, and currencies) quickly, easily, relatively inexpensively, and without having to hold directly any of the underlying assets, options for bitcoin exposure for U.S. investors remain limited to: (i) Investing in over-the-counter bitcoin funds (“OTC Bitcoin Funds”) that are subject to high premium/discount volatility (and high management fees) to the advantage of more sophisticated investors that are able to create and potentially redeem shares at net asset value (“NAV”) directly with the issuing trust; (ii) facing the technical risk, complexity and generally high fees associated with buying spot bitcoin; or (iii) purchasing shares of operating companies that they believe will provide proxy exposure to bitcoin with limited disclosure about the associated risks. Meanwhile, investors in many other countries, including Canada,[36]                                          are able to use more traditional exchange listed and traded products to gain exposure to bitcoin, disadvantaging U.S. investors and leaving them with riskier and more expensive means of getting bitcoin exposure.[37] 

#### OTC Bitcoin Funds and Investor Protection

Over the past year, U.S. investor exposure to bitcoin through OTC Bitcoin Funds has grown into the tens of billions of dollars. With that growth, so too has grown the potential risk to U.S. investors. As described below, premium and discount volatility, high fees, insufficient disclosures, and technical hurdles are putting U.S. investor money at risk on a daily basis that could potentially be eliminated through access to a bitcoin ETP. The Exchange understands the Commission's previous focus on potential manipulation of a bitcoin ETP in prior disapproval orders, but now believes that such concerns have been sufficiently mitigated and that the growing and quantifiable investor protection concerns should be the central consideration as the Commission reviews this proposal. As such, the Exchange believes that approving this proposal (and comparable proposals submitted hereafter) 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 associated with investing in operating companies that are imperfect proxies for bitcoin exposure; and (iv) providing an alternative to custodying spot bitcoin.

#### (i) OTC Bitcoin Funds and Premium/Discount Volatility

                    OTC Bitcoin Funds are generally designed to provide exposure to bitcoin in a manner similar to the Shares. However, unlike the Shares, OTC Bitcoin Funds are unable to freely offer creation and redemption in a way that incentivizes market participants to keep their shares trading in line with their NAV [38]                                          and, as such, frequently trade at a price that is out of line with the value of their assets held. Historically, OTC Bitcoin Funds have traded at a significant premium to NAV.[39] 

                    Trading at a premium or a discount is not unique to OTC Bitcoin Funds and is not in itself problematic, but the size of such premiums/discounts and volatility thereof highlight the key differences in operations and market structure of OTC Bitcoin Funds as compared to ETPs. This, combined with the significant increase in AUM for OTC Bitcoin Funds over the past year, has given rise to significant and quantifiable investor protection issues, as further described below. In fact, the largest OTC Bitcoin Fund has grown to $38.3 billion in AUM [40]                                          and has historically traded at a premium of between roughly five and 40%, though it has seen premiums at times above 100%.[41]                                          Recently, however, it has traded at a discount. As of June 18, 2021, the discount was approximately 11%, representing around $4.1 billion in market value less than the bitcoin actually held by the fund. If premium/discount numbers                           ( print page 43293)                        move back to the middle of its historical range to a 20% premium (which historically could occur at any time and overnight), it would represent a swing of approximately $11 billion in value unrelated to the value of bitcoin held by the fund. These numbers are only associated with a single OTC Bitcoin Fund—as more and more OTC Bitcoin Funds come to market and more investor assets flood into them to get access to bitcoin exposure, the potential dollars at risk will only increase.                

This raises significant investor protection issues in several ways. First, the most obvious issue is that investors are buying shares of a fund for a price that is not reflective of the per share value of the fund's underlying assets. Even operating within the normal premium 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/discount. As more investment vehicles, including mutual funds and ETFs, seek to gain exposure to bitcoin, the easiest option for a buy and hold strategy 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.

The second issue is related to the first and explains how the premium in OTC Bitcoin Funds essentially creates a direct payment from retail investors to more sophisticated investors. Generally speaking, only accredited investors are able to create or redeem shares with the issuing trust, which means that they are able to buy or sell shares directly with the trust at NAV (in exchange for either cash or bitcoin) without having to pay the premium or sell into the discount. While there are often minimum holding periods for shares, an investor that is allowed to interact directly with the trust is able to hedge their bitcoin exposure as needed to satisfy the holding requirements and collect on the premium or discount opportunity.

                    As noted above, the existence of a premium or discount and the premium/discount collection opportunity is not unique to OTC Bitcoin Funds and does not in itself warrant the approval of an ETP.[42]                                          What makes this situation unique is that such significant and persistent premiums and discounts can exist in a product with $30+ billion in assets under management,[43]                                          that billions of retail investor dollars are constantly under threat of premium/discount volatility,[44]                                          and that premium/discount volatility is generally captured by more sophisticated investors on a riskless basis. The Exchange understands the Commission's focus on potential manipulation of a bitcoin ETP in prior disapproval orders, but now believes that current circumstances warrant that this direct, quantifiable investor protection issue should be the central consideration as the Commission determines whether to approve this proposal, particularly when the Trust as a bitcoin ETP is designed to reduce the likelihood of significant and prolonged premiums and discounts with its open-ended nature as well as the ability of market participants (                    *i.e.,*                     market makers and authorized participants) to create and redeem on a daily basis.                

#### (ii) Spot and Proxy Exposure

                    Exposure to bitcoin through an ETP also presents certain advantages for retail investors compared to buying spot bitcoin directly. The most notable advantage is the use of the Custodian to custody the Trust's bitcoin assets. The Sponsor has carefully selected the Custodian, a third party custodian that carries insurance covering both hot and cold storage and is chartered as a trust company and will custody the Trust's bitcoin assets in a manner so that it meets the definition of qualified custodian under the Investment Advisers Act of 1940, as amended. This includes, among others, the use of “cold” (offline) storage to hold private keys and the employment by the Custodian of a certain degree of cybersecurity measures and operational best practices. By contrast, an individual retail investor holding bitcoin through a cryptocurrency exchange lacks these protections. Typically, retail exchanges hold most, if not all, retail investors' bitcoin in “hot” (internet-connected) storage and do not make any commitments to indemnify retail investors or to observe any particular cybersecurity standard. Meanwhile, a retail investor holding spot bitcoin directly in a self-hosted wallet may suffer from inexperience in private key management (                    *e.g.,*                     insufficient password protection, lost key, etc.), which could cause them to lose some or all of their bitcoin holdings. In the Custodian, the Trust has engaged a regulated and licensed entity highly experienced in bitcoin custody, with dedicated, trained employees and procedures to manage the private keys to the Trust's bitcoin, and which is accountable for failures. Thus, with respect to custody of the Trust's bitcoin assets, the Trust presents advantages from an investment protection standpoint for retail investors compared to owning spot bitcoin directly.                

                    Finally, as described in the Background section above, recently 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 $1.5 billion in bitcoin.[45]                                          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.[46]                                          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.[47]                                          Such operating companies,                           ( print page 43294)                        however, are imperfect bitcoin proxies and provide investors with partial bitcoin exposure paired with a host of additional risks associated with whichever operating company they decide to purchase. Additionally, the disclosures provided by the aforementioned operating companies with respect to risks relating to their bitcoin holdings are generally substantially smaller than the registration statement of a bitcoin ETP, including the Registration Statement, typically amounting to a few sentences of narrative description and a handful of risk factors.[48]                                          In other words, investors seeking bitcoin exposure through publicly traded companies are gaining only partial exposure to bitcoin and are not fully benefitting from the risk disclosures and associated investor protections that come from the securities registration process.                

#### Bitcoin Futures

                    CME began offering trading in Bitcoin Futures in 2017. Each contract represents five bitcoin and is based on the CME CF Bitcoin Reference Rate.[49]                                          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 and/or accelerated upward in the past year. For example, there was approximately $28 billion in trading in Bitcoin Futures in December 2020 compared to $737 million, $1.4 billion, and $3.9 billion in total trading in December 2017, December 2018, and December 2019, respectively. Bitcoin Futures traded over $1.2 billion per day on the CME in December 2020 and represented $1.6 billion in open interest compared to $115 million in December 2019. This general upward trend in trading volume and open interest is captured in the following chart.                
      ( print page 43295)    
                    Similarly, the number of large open interest holders [50]                                          has continued to increase even as the price of bitcoin has risen, as have the number of unique accounts trading Bitcoin Futures.                
      ( print page 43296)    
                    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 that bitcoin futures lead the bitcoin spot market in price formation.[51] 

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

                    The Commission has approved numerous series of Trust Issued Receipts,[52]                                          including Commodity-Based Trust Shares,[53]                                          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; [54]                                          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 it has sufficiently demonstrated 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. Specifically, the Exchange lays out below why it believes that the significant increase in trading volume in Bitcoin Futures, the growth of liquidity at the inside in the spot market for bitcoin, and certain features of the Shares and the Index (as defined below) mitigate potential manipulation concerns to the point that the investor protection issues that have arisen from the rapid growth of over-the-counter bitcoin funds since the Commission last reviewed an exchange proposal to list and trade a bitcoin ETP, including premium/discount volatility and management fees, should be the central consideration as the Commission determines whether to approve 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 [55]                                          with a regulated market of significant size. Both the Exchange and CME are members of the Intermarket Surveillance Group (the “ISG”).[56]                                          The only remaining issue to be addressed is whether the Bitcoin Futures market constitutes a market of significant size, which the Exchange believes 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.[57] 

                    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.[58] 

#### (a) Manipulation of the ETP

                    The significant growth in Bitcoin Futures across each of trading volumes, open interest, large open interest holders, and total market participants since the Wilshire Phoenix Disapproval was issued are reflective of that market's growing influence on the spot price, which according to the academic research cited above, was already leading the spot price in 2018 and 2019. 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 [59]                                         ) would have to participate in                           ( print page 43297)                        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. Further, the Trust only allows for in-kind creation and redemption, which, as further described below, reduces the potential for manipulation of the Shares through manipulation of the Index or any of its individual constituents, again emphasizing that a potential manipulator of the Shares would have to manipulate the entirety of the bitcoin spot market, which is led by the Bitcoin Futures market. 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 also believes 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 (approximately $650 billion), 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. According to data from CoinRoutes from February 2021, the cost to buy or sell $5 million worth of bitcoin averages roughly 10 basis points with a market impact of 30 basis points.[60]                                          For a $10 million market order, the cost to buy or sell is roughly 20 basis points with a market impact of 50 basis points. Stated another way, a market participant could enter a market buy or sell order for $10 million of bitcoin and only move the market 0.5%. More strategic purchases or sales (such as using limit orders and executing through OTC bitcoin trade desks) would likely have less obvious impact on the market—which is consistent with MicroStrategy, Tesla, and Square being able to collectively purchase billions of dollars in bitcoin. As such, the combination of Bitcoin Futures leading price discovery, the overall size of the bitcoin market, and the ability for market participants, including authorized participants creating and redeeming in-kind with the Trust, to buy or sell large amounts of bitcoin without significant market impact will help prevent the Shares from becoming the predominant force on pricing in either the bitcoin spot or Bitcoin Futures markets, satisfying part (b) of the test outlined above.                

#### (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 believes that such conditions are present. Specifically, the significant liquidity in the spot market and the impact of market orders on the overall price of bitcoin mean that attempting to move the price of bitcoin is costly and has grown more expensive over the past year. In January 2020, for example, the cost to buy or sell $5 million worth of bitcoin averaged roughly 30 basis points (compared to 10 basis points in 2/2021) with a market impact of 50 basis points (compared to 30 basis points in 2/2021).[61]                                          For a $10 million market order, the cost to buy or sell was roughly 50 basis points (compared to 20 basis points in 2/2021) with a market impact of 80 basis points (compared to 50 basis points in 2/2021). As the liquidity in the bitcoin spot market increases, it follows that the impact of $5 million and $10 million orders will continue to decrease the overall impact in spot price.                

                    Additionally, offering only in-kind creation and redemption will provide unique protections against potential attempts to manipulate the Shares. While the Sponsor believes that the Index which it uses to value the Trust's bitcoin is itself resistant to manipulation based on the methodology further described below, the fact that creations and redemptions are only available in-kind makes the manipulability of the Index significantly less important. Specifically, because the Trust will not accept cash to buy bitcoin in order to create new shares or, barring a forced redemption of the Trust or under other extraordinary circumstances, be forced to sell bitcoin to pay cash for redeemed shares, the price that the Sponsor uses to value the Trust's bitcoin is not particularly important.[62]                                          When authorized participants are creating with the Trust, they need to deliver a certain number of bitcoin per share (regardless of the valuation used) and when they're redeeming, they can similarly expect to receive a certain number of bitcoin per share. As such, even if the price used to value the Trust's bitcoin is manipulated (which the Sponsor believes that its methodology is resistant to), the ratio of bitcoin per Share does not change and the Trust will either accept (for creations) or distribute (for redemptions) the same number of bitcoin regardless of the value. This not only mitigates the risk associated with potential manipulation, but also discourages and disincentivizes manipulation of the Index because there is little financial incentive to do so.                

#### 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 (“ARK”) will provide assistance in the marketing of the Shares. Coinbase Custody Trust Company, LLC, a third-party regulated custodian (the “Custodian”), will be responsible for custody of the Trust's bitcoin.

According to the Registration Statement, each Share will represent a fractional undivided beneficial interest in the bitcoin held by the Trust. The Trust's assets will consist of bitcoin held by the Custodian on behalf of the Trust. The Trust generally does not intend to hold cash or cash equivalents. However, there may be situations where the Trust will unexpectedly hold cash on a temporary basis.

                    According to the Registration Statement, the Trust is neither an investment company registered under the Investment Company Act of 1940, as amended,[63]                                          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 sells or redeems its Shares, it will do so in “in-kind”                           ( print page 43298)                        transactions in blocks of 5,000 Shares (a “Creation Basket”) at the Trust's NAV. Authorized participants will deliver, or facilitate the delivery of, bitcoin to the Trust's account with the Custodian in exchange for Shares when they purchase Shares, and the Trust, through the Custodian, will deliver bitcoin 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. Shareholders who buy or sell Shares during the day from their broker may do so at a premium or discount relative to the NAV of the Shares of the Trust.                

#### 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 S&P Bitcoin Index (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-kind in transactions with authorized participants. The Trust is not actively managed.

#### The Index

As described in the Registration Statement, the Fund will use the Index to calculate the Trust's NAV. The Index is a U.S. dollar-denominated composite reference rate for the price of bitcoin. There is no component other than bitcoin in the Index. The underlying exchanges are sourced by Lukka Inc. (the “Data Provider”) based on a combination of qualitative and quantitative metrics to analyze a comprehensive data set and evaluate factors including legal/regulation, KYC/transaction risk, data provision, security, team/exchange, asset quality/diversity, market quality and negative events. The Index price is currently sourced from the following set of exchanges: Binance, Bitfinex, Bitflyer, Bittrex, Bitstamp, Coinbase Pro, Gemini, HitBTC, Huobi, Kraken, KuCoin, and Poloniex.

The Index methodology is intended to determine the fair market value (“FMV”) for bitcoin by determining the principal market for bitcoin as of 4pm ET daily. The Index methodology uses a ranking approach that considers several exchange characteristics including oversight and intra-day trading volume. Specifically, to rank the credibility and quality of each exchange, the Data Provider dynamically assigns a Base Exchange Score (“BES”) score to the key characteristics for each exchange.

The BES reflects the fundamentals of an exchange and determines which exchange should be designated as the principal market at a given point of time. This score is determined by computing a weighted average of the values assigned to four different exchange characteristics. All new and existing exchanges have to be approved by Lukka's Price Integrity Oversight Board at quarterly meetings. The exchange characteristics are as follows: (i) Oversight; (ii) microstructure efficiency; (iii) data transparency and (iv) data integrity.

#### Oversight

This score reflects the rules in place to protect and to give access to the investor. The score assigned for exchange oversight will depend on parameters such as jurisdiction, regulation, “Know Your Customer and Anti-Money Laundering Compliance” (KYC/AML), among other proprietary factors.

#### Microstructure Efficiency

The effective bid ask spread is used as a proxy for efficiency. For example, for each exchange and currency pair, the Data Provider takes an estimate of the “effective spread” relative to the price.

#### Data Transparency

Transparency is the term used for a quality score that is determined by the level of detail of the data offered by an exchange. The most transparent exchanges offer order-level data, followed by order book, trade-level, and then candles.

#### Data Integrity

Data integrity reconstructs orders to ensure the transaction amounts that make up an order equal the overall order amount matching on both a minute and daily basis. This data would help expose nefarious actions such as wash trading or other potential manipulation of data.

The methodology then applies a five-step weighting process for identifying a principal exchange and the last price on that exchange. Following this weighting process, an executed exchange price is assigned for bitcoin as of 4 p.m. ET. The Index price is determined according to the following procedure:
    -  Step 1:                      Assign each exchange a Base Exchange Score (“BES”) reflecting static exchange characteristics such as oversight, microstructure and technology, as discussed below.                
    -  Step 2:                      Adjust the BES based on the relative monthly volume each exchange services. This new score is the Volume Adjusted Score (“VAS”).                
    -  Step 3:                      Decay the VAS based on the time passed since the last trade on the exchange. Here, the Data Provider is assessing the level of activity in the market by considering the frequency (volume) of trades. The decay factor reflects the time since the last trade on the exchange. This is the final Decayed Volume Adjusted Score (“DVAS”), which tracks the freshness of the data by tracking most recent trades.                
    -  Step 4:                      Rank the exchanges by the DVAS score and designate the highest-ranking exchange as the principal market for that point in time. The principal market is the exchange with the highest DVAS.                
    -  Step 5:                      After selecting a primary exchange, an executed exchange price is used for bitcoin representing FMV at 4 p.m. ET. The Data Provider takes the last traded prices at that moment in time on that trading venue for the relevant pair (Bitcoin/USD) when determining the Index price.                

As discussed in the Registration Statement, the fact that there are multiple bitcoin spot markets that may contribute prices to the Index price makes manipulation more difficult in a well-arbitraged and fractured market, as a malicious actor would need to manipulate multiple spot markets simultaneously to impact the Index price, or dramatically skew the historical distribution of volume between the various exchanges.

The Data Provider has dedicated resources and committees established to ensure all prices are representative of the market. Any price challenges will result in an independent analysis of the price. This includes assessing whether the price from the selected exchange is biased according to analyses designed to recognize patterns consistent with manipulative activity, such as a quick reversion to previous traded levels following a sharp price change or any significant deviations from the volume weighted average price on a particular exchange or pricing on any other exchange included in the Lukka Prime eligibility universe.

                    Upon detection or external referral of suspect manipulative activities, the case will be assigned a team of quantitative experts for mandatory investigation. These checks occur on an on-going, intraday basis and any investigations are typically resolved same day. The evidence uncovered shall be turned over to the Data Provider's Price Integrity                           ( print page 43299)                        Oversight Board for final decision and action. The Price Integrity Oversight Board may choose to pick an alternative primary market and may exclude such market from future inclusion in the Index methodology or choose to stand by the original published price upon fully evaluating all available evidence. It may also initiate an investigation of prior prices from such market and shall evaluate evidence presented on a case-by-case basis.                

#### 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 Trust will provide an Intraday Indicative Value (“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 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 will be widely disseminated on a per Share basis every 15 seconds during the Exchange's Regular Trading Hours by one or more major market data vendors. In addition, the IIV will be available through on-line information services.

                    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 [64]                                          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 Trust will also disseminate the Trust's holdings on a daily basis on the Trust's website. 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. Information about the Index, including key elements of how the Index is calculated, will be publicly available at                     *https://www.spglobal.com/​spdji/​en/​indices/​digital-assets/​sp-bitcoin-index/​.*

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. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the Consolidated Tape Association (“CTA”).

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

#### Net Asset Value

NAV means the total assets of the Trust including, but not limited to, all bitcoin and cash less total liabilities of the Trust, each determined on the basis of generally accepted accounting principles. 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.

#### Creation and Redemption of Shares

According to the Registration Statement, on any business day, an authorized participant may place an order to create one or more baskets. Purchase orders must be placed by 4:00 p.m. Eastern Time, or the close of regular trading on the Exchange, whichever is earlier. The day on which an order is received is considered the purchase order date. The total deposit of bitcoin required is an amount of bitcoin that is in the same proportion to the total assets of the Trust, net of accrued expenses and other liabilities, on the date the order to purchase is properly received, as the number of Shares to be created under the purchase order is in proportion to the total number of Shares outstanding on the date the order is received. Each night, the Sponsor will publish the amount of bitcoin that will be required in exchange for each creation order. The Administrator determines the required deposit 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. The procedures by which an authorized participant can redeem one or more Creation Baskets mirror the procedures for the creation of Creation Baskets.

#### 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 will obtain a representation that the Trust's NAV will be calculated daily and that these values and information about 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 a specified commodity [65]                                          deposited with the trust; (b) issued by such trust in a specified aggregate minimum number in return for a deposit of a quantity of the underlying commodity; 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.                

                    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                           ( print page 43300)                        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.                

#### Trading Halts

With respect to trading halts, the Exchange may consider all relevant 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.

#### 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.

#### Surveillance

                    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 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.[66] 

#### 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 [67]                                          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.                

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 [68]                                          in general and Section 6(b)(5) of the Act [69]                                          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,[70]                                          including Commodity-Based                           ( print page 43301)                        Trust Shares,[71]                                          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; [72]                                          and (ii) the requirement that an exchange proposal be designed, in general, to protect investors and the public interest.                

                    The Exchange believes that the proposal is, in particular, designed to protect investors and the public interest. With the growth of OTC Bitcoin Funds over the past year, so too has grown the potential risk to U.S. investors. Significant and prolonged premiums and discounts, significant premium/discount volatility, high fees, insufficient disclosures, and technical hurdles are putting U.S. investor money at risk on a daily basis that could potentially be eliminated through access to a bitcoin ETP. As such, the Exchange believes that this proposal acts to limit the risk to U.S. investors that are increasingly seeking exposure to bitcoin through the elimination of significant and prolonged premiums and discounts, significant premium/discount volatility, the reduction of management fees through meaningful competition, the avoidance of risks associated with investing in operating companies that are imperfect proxies for bitcoin exposure, and protection from risk associated with custodying spot bitcoin by providing direct, 1-for-1 exposure to bitcoin in a regulated, transparent, exchange-traded vehicle designed to reduce the likelihood of significant and prolonged premiums and discounts with its open-ended nature as well as the ability of market participants (                    *i.e.,*                     market makers and authorized participants) to create and redeem on a daily basis.                

The Exchange also believes that this proposal is consistent with the requirements of Section 6(b)(5) of the Act and that it has sufficiently demonstrated 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. Specifically, the Exchange believes that the significant increase in trading volume in Bitcoin Futures, the growth of liquidity at the inside in the spot market for bitcoin, and certain features of the Shares and the Index mitigate potential manipulation concerns to the point that the investor protection issues that have arisen from the rapid growth of over-the-counter bitcoin funds since the Commission last reviewed an exchange proposal to list and trade a bitcoin ETP, including premium/discount volatility and management fees, should be the central consideration as the Commission determines whether to approve 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 [73]                                          with a regulated market of significant size. Both the Exchange and CME are members of ISG.[74]                                          The only remaining issue to be addressed is whether the Bitcoin Futures market constitutes a market of significant size, which the Exchange believes 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.[75] 

                    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.[76] 

#### (a) Manipulation of the ETP

The significant growth in Bitcoin Futures across each of trading volumes, open interest, large open interest holders, and total market participants since the Wilshire Phoenix Disapproval was issued are reflective of that market's growing influence on the spot price, which according to the academic research cited above, was already leading the spot price in 2018 and 2019. 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) 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. Further, the Trust only allows for in-kind creation and redemption, which, as further described below, reduces the potential for manipulation of the Shares through manipulation of the Index or any of its individual constituents, again emphasizing that a potential manipulator of the Shares would have to manipulate the entirety of the bitcoin spot market, which is led by the Bitcoin Futures market. 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 also believes that trading in the Shares would not be the predominant force on prices in the Bitcoin Futures market (or spot market)                           ( print page 43302)                        for a number of reasons, including the significant volume in the Bitcoin Futures market, the size of bitcoin's market cap (approximately $650 billion), 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. According to data from CoinRoutes from February 2021, the cost to buy or sell $5 million worth of bitcoin averages roughly 10 basis points with a market impact of 30 basis points.[77]                                          For a $10 million market order, the cost to buy or sell is roughly 20 basis points with a market impact of 50 basis points. Stated another way, a market participant could enter a market buy or sell order for $10 million of bitcoin and only move the market 0.5%. More strategic purchases or sales (such as using limit orders and executing through OTC bitcoin trade desks) would likely have less obvious impact on the market—which is consistent with MicroStrategy, Tesla, and Square being able to collectively purchase billions of dollars in bitcoin. As such, the combination of Bitcoin Futures leading price discovery, the overall size of the bitcoin market, and the ability for market participants, including authorized participants creating and redeeming in-kind with the Trust, to buy or sell large amounts of bitcoin without significant market impact will help prevent the Shares from becoming the predominant force on pricing in either the bitcoin spot or Bitcoin Futures markets, satisfying part (b) of the test outlined above.                

#### (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 believes that such conditions are present. Specifically, the significant liquidity in the spot market and the impact of market orders on the overall price of bitcoin mean that attempting to move the price of bitcoin is costly and has grown more expensive over the past year. In January 2020, for example, the cost to buy or sell $5 million worth of bitcoin averaged roughly 30 basis points (compared to 10 basis points in 2/2021) with a market impact of 50 basis points (compared to 30 basis points in 2/2021).[78]                                          For a $10 million market order, the cost to buy or sell was roughly 50 basis points (compared to 20 basis points in 2/2021) with a market impact of 80 basis points (compared to 50 basis points in 2/2021). As the liquidity in the bitcoin spot market increases, it follows that the impact of $5 million and $10 million orders will continue to decrease the overall impact in spot price.                

                    Additionally, offering only in-kind creation and redemption will provide unique protections against potential attempts to manipulate the Shares and the Sponsor notes that it has operated numerous products on this basis since 2018. While the Sponsor believes that the Index which it uses to value the Trust's bitcoin is itself resistant to manipulation based on the methodology described above, the fact that creations and redemptions are only available in-kind makes the manipulability of the Index significantly less important. Specifically, because the Trust will not accept cash to buy bitcoin in order to create new shares or, barring a forced redemption of the Trust or under other extraordinary circumstances, be forced to sell bitcoin to pay cash for redeemed shares, the price that the Sponsor uses to value the Trust's bitcoin is not particularly important.[79]                                          When authorized participants are creating with the Trust, they need to deliver a certain number of bitcoin per share (regardless of the valuation used) and when they're redeeming, they can similarly expect to receive a certain number of bitcoin per share. As such, even if the price used to value the Trust's bitcoin is manipulated (which the Sponsor believes that its methodology is resistant to), the ratio of bitcoin per Share does not change and the Trust will either accept (for creations) or distribute (for redemptions) the same number of bitcoin regardless of the value. This not only mitigates the risk associated with potential manipulation, but also discourages and disincentivizes manipulation of the Index because there is little financial incentive to do so.                

#### 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 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 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 will be widely disseminated on a per Share basis every 15 seconds during the Exchange's Regular Trading Hours by one or more major market data vendors. In addition, the IIV will be available through on-line information services.                          ( print page 43303)    

                    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 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 Trust will also disseminate the Trust's holdings on a daily basis on the Trust's website. 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. Information about the Index, including key elements of how the Index is calculated, will be publicly available at                     *https://www.spglobal.com/​spdji/​en/​indices/​digital-assets/​sp-bitcoin-index/​.*

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. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the CTA.

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

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.

## III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

                    Within 45 days of the date of publication of this notice in the                     **Federal Register**                     or within such longer period up to 90 days (i) as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or (ii) as to which the Exchange consents, the Commission will:                

A. By order approve or disapprove such proposed rule change, or

B. institute proceedings to determine whether the proposed rule change should be disapproved.

36.                             The Exchange notes that the Purpose Bitcoin ETF, a retail physical bitcoin ETP recently launched in Canada, reportedly reached $421.8 million in assets under management (“AUM”) in two days, demonstrating the demand for a North American market listed bitcoin exchange-traded product (“ETP”). The Purpose Bitcoin ETF also offers a class of units that is U.S. dollar denominated, which could appeal to U.S. investors. Without an approved bitcoin ETP in the U.S. as a viable alternative, U.S. investors could seek to purchase these shares 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.

37.                             The Exchange notes that securities regulators in a number of other countries have either approved or otherwise allowed the listing and trading of bitcoin ETPs. Specifically, these funds include the Purpose Bitcoin ETF, Bitcoin ETF, VanEck Vectors Bitcoin ETN, WisdomTree Bitcoin ETP, Bitcoin Tracker One, BTCetc bitcoin ETP, Amun Bitcoin ETP, Amun Bitcoin Suisse ETP, 21Shares Short Bitcoin ETP, and CoinShares Physical Bitcoin ETP.

38.                             Because OTC Bitcoin Funds are not listed on an exchange, they are also not subject to the same transparency and regulatory oversight by a listing exchange as the Shares would be. In the case of the Trust, the existence of a surveillance-sharing agreement between the Exchange and the Bitcoin Futures market results in increased investor protections compared to OTC Bitcoin Funds.

39.                             The inability to trade in line with NAV may at some point result in OTC Bitcoin Funds trading at a discount to their NAV, which has occurred more recently with respect to one prominent OTC Bitcoin Fund. While that has not historically been the case, and it is not clear whether such discounts will continue, such a prolonged, significant discount scenario would give rise to nearly identical potential issues related to trading at a premium as described below.

While the price of one bitcoin has increased approximately 400% in the intervening period, the total AUM has increased by approximately 1240%, indicating that the increase in AUM was created beyond just price appreciation in bitcoin.

50.                             A large open interest holder in Bitcoin Futures is an entity that holds at least 25 contracts, which is the equivalent of 125 bitcoin. At a price of approximately $30,000 per bitcoin on 12/31/20, more than 80 firms had outstanding positions of greater than $3.8 million in Bitcoin Futures.

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.”

54.                             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 exchanges 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 exchange 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 exchange 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.

55.                             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 ISG constitutes such a surveillance sharing agreement.                         *See*                         Wilshire Phoenix Disapproval.
