 Exhibit 4.6 

DESCRIPTION OF SECURITIES REGISTERED UNDER SECTION 12 OF THE SECURITIES 

EXCHANGE ACT OF 1934 
 The following is a
summary of the rights of the common units of fractional undivided beneficial interest (the “Shares”) of Grayscale Bitcoin Trust (BTC) (the “Trust”), which is the only class of securities of the Trust that is registered under
Section 12 of the Securities Exchange Act of 1934 (the “Exchange Act”). The description is intended as a summary, and is qualified in its entirety by reference the Fifth Amended and Restated Declaration of Trust and Trust Agreement,
as amended by Amendments No. 1 and No. 2 thereto, copies of which have been filed as exhibits to this annual report on Form 10-K. Terms used but not defined herein have the meaning set forth in the
Glossary of Terms in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2019, of which this exhibit is a part. 

General 
 The Trust operates pursuant to
the Fifth Amended and Restated Declaration of Trust and Trust Agreement between Delaware Trust Company (formerly known as CSC Trust Company of Delaware), a Delaware trust company and Delaware trustee of the Trust (the “Trustee”) and
Grayscale Investments, LLC (the “Sponsor”), as amended by Amendments No. 1 and No. 2 thereto and as the same may be amended from time to time (as so amended, the “Trust Agreement”). Under the Trust Agreement, the Trust
is authorized to create and issue an unlimited number of Shares. Shares will be issued only in Baskets (a Basket equals a block of 100 Shares) in connection with creations. The Shares represent units of fractional undivided beneficial interest in
and ownership of the Trust and have no par value. The Shares are quoted on OTCQX under the ticker symbol “GBTC.” 
 Description of Limited
Rights 
 The Shares do not represent a traditional investment and should not be viewed as similar to “shares” of a corporation
operating a business enterprise with management and a board of directors. A Shareholder will not have the statutory rights normally associated with the ownership of shares of a corporation. Each Share is transferable, is fully paid and non-assessable and entitles the holder to vote on the limited matters upon which Shareholders may vote under the Trust Agreement. For example, Shareholders do not have the right to elect directors and will not
receive dividends. The Shares do not entitle their holders to any conversion or pre-emptive rights or, except as discussed below, any redemption rights or rights to distributions. 

Voting and Approvals 
 The Shareholders
take no part in the management or control of the Trust. Under the Trust Agreement, Shareholders have limited voting rights. For example, in the event that the Sponsor withdraws, a majority of the Shareholders may elect and appoint a successor
sponsor to carry out the affairs of the Trust. In addition, no amendments to the Trust Agreement that materially adversely affect the interests of Shareholders may be made without the vote of at least a majority (over 50%) of the Shares (not
including any Shares held by the Sponsor or its affiliates). However, the Sponsor may make any other amendments to the Trust Agreement in its sole discretion without Shareholder consent provided that the Sponsor provides 20 days’ notice of any
such amendment. 
 Derivative Actions 

Under Delaware law, a shareholder may bring a derivative action if the shareholder is a shareholder at the time the action is brought and
either (i) was a shareholder at the time of the transaction at issue or (ii) acquired the status of shareholder by operation of law or the Trust’s governing instrument from a person who was a shareholder at the time of the transaction
at issue. Additionally, Section 3816(e) of the Delaware Statutory Trust Act specifically provides that “a beneficial owner’s right to bring a derivative action may be subject to such additional standards and restrictions, if any, as
are set forth in the governing instrument of the statutory trust, including, without limitation, the requirement that beneficial owners owning a specified beneficial interest in the statutory trust join in the bringing of the derivative
action.” In addition to the requirements of applicable law, Section 7.4 of the Trust Agreement provides that no Shareholder will have the right, power or authority to bring or maintain a derivative action, suit or other proceeding on
behalf of the Trust unless two or more Shareholders who (i) are not affiliates of one another and (ii) collectively hold at least 10.0% of the outstanding Shares join in the bringing or maintaining of such action, suit or other proceeding.
The Trust selected the 10.0% ownership threshold because the Trust believed that this was a threshold that investors would be comfortable with based on market precedent. 

 This provision applies to any derivative action brought in the name of the Trust other than
claims brought under the federal securities laws or the rules and regulations thereunder, to which Section 7.4 does not apply. Due to this additional requirement, a Shareholder attempting to bring a derivative action in the name of the Trust
will be required to locate other Shareholders with which it is not affiliated and that have sufficient Shares to meet the 10.0% threshold based on the number of Shares outstanding on the date the claim is brought and thereafter throughout the
duration of the action, suit or proceeding. 
 Distributions 

Pursuant to the terms of the Trust Agreement, the Trust may make distributions on the Shares in-cash or
in-kind, including in such form as is necessary or permissible for the Trust to facilitate Shareholders’ access to any Incidental Rights or to IR Virtual Currency. 

In addition, if the Trust is terminated and liquidated, the Sponsor will distribute to the Shareholders any amounts of the cash proceeds of
the liquidation remaining after the satisfaction of all outstanding liabilities of the Trust and the establishment of reserves for applicable taxes, other governmental charges and contingent or future liabilities as the Sponsor will determine. See
“Item 1. Business—Description of the Trust Agreement—The Trustee—Termination of the Trust” in the Trust’s Annual Report on Form 10-K, of which this exhibit is a part. Shareholders
of record on the record date fixed by the Transfer Agent for a distribution will be entitled to receive their pro rata portions of any distribution. 

Appointment of Agent 
 Pursuant to the
terms of the Trust Agreement, by holding the Shares, Shareholders will be deemed to agree that the Sponsor may cause the Trust to appoint an agent (any person appointed in such capacity, an “Agent”) to act on their behalf in connection
with any distribution of Incidental Rights and/or IR Virtual Currency if the Sponsor has determined in good faith that such appointment is reasonably necessary or in the best interests of the Trust and the Shareholders in order to facilitate the
distribution of any Incidental Rights and/or IR Virtual Currency. The Sponsor may cause the Trust to appoint Grayscale Investments, LLC (acting other than in its capacity as Sponsor) or any of its affiliates to act in such capacity. 

Any Agent appointed to facilitate a distribution of Incidental Rights and/or IR Virtual Currency will receive an in-kind distribution of Incidental Rights and/or IR Virtual Currency on behalf of the Shareholders of record with respect to such distribution, and following receipt of such distribution, will determine, in its sole
discretion and without any direction from the Trust, or the Sponsor, in its capacity as Sponsor of the Trust, whether and when to sell the distributed Incidental Rights and/or IR Virtual Currency on behalf of the record date Shareholders. If the
Agent is able to do so, it will remit the cash proceeds to the record date Shareholders. There can be no assurance as to the price or prices for any Incidental Rights and/or IR Virtual Currency that the Agent may realize, and the value of the
Incidental Rights and/or IR Virtual Currency may increase or decrease after any sale by the Agent. 
 Any Agent appointed pursuant to the
Trust Agreement will not receive any compensation in connection with its role as agent. However, any Agent will be entitled to receive from the record-date Shareholders, out of the distributed Incidental Rights and/or IR Virtual Currency, an amount
of Incidental Rights and/or IR Virtual Currency with an aggregate fair market value equal to the amount of administrative and other reasonable expenses incurred by the Agent in connection with its activities as agent of the record-date Shareholders,
including expenses incurred by the Agent in connection with any post-distribution sale of such Incidental Rights and/or IR Virtual Currency. 

In the past, the Sponsor has caused the Trust to appoint Grayscale Investments, LLC, acting other than in its capacity as Sponsor, as Agent to
facilitate the distribution of Incidental Rights and/or IR Virtual Currency to Shareholders. The Trust has no right to receive any information about any distributed Incidental Rights and/or IR Virtual Currency or the disposition thereof from the
record date Shareholders, their Agent or any other person. 

 Creation of Shares 

The Trust creates Shares such times and for such periods as determined by the Sponsor, but only in one or more whole Baskets. A Basket equals
100 Shares. See “Item 1. Business—Description of Creation of Shares” in the Trust’s Annual Report on Form 10-K, of which this exhibit is a part. The creation of a Basket requires the
delivery to the Trust of the number of Bitcoins represented by one Share immediately prior to such creation multiplied by 100. The Trust may from time to time halt creations. As a result, the Shares may trade at a substantial premium over, or
substantial discount to, the value of the Trust’s Bitcoin Holdings per Share. This is because Authorized Participants would not be able to take advantage of arbitrage opportunities created when the market value of the Shares deviates from the
value of the Trust’s Bitcoin Holdings per Share. 
 Redemption of Shares 

The Trust Agreement also provides for the redemption procedures. However, redemption of Shares are currently not permitted and the Trust is
unable to redeem Shares. Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. Because the Trust does not believe that the SEC
would, at this time, entertain an application for the waiver of rules needed in order to operate an ongoing redemption program, the Trust currently has no intention of seeking regulatory approval from the SEC to operate an ongoing redemption
program. 
 Even if such relief is sought in the future, no assurance can be given as to the timing of such relief or that such
relief will be granted. If such relief is granted and the Sponsor approves a redemption program, the Shares will be redeemable only in accordance with the provisions of the Trust Agreement and the relevant Participant Agreement. See “Item 1A.
Risk Factors—Risk Factors Related to the Trust and the Shares—Because of the holding period under Rule 144 and the lack of an ongoing redemption program, there is no arbitrage mechanism to keep the price of the Shares closely linked to the
Bitcoin Index Price and the Shares have historically traded at a substantial premium over the Bitcoin Holdings per Share” and “Item IA. Risk Factors—Risk Factors Related to the Trust and the Shares—The restrictions on transfer
and redemption may result in losses on the value of the Shares” in the Trust’s Annual Report on Form 10-K, of which this exhibit is a part. 

Transfer Restrictions 
 Shares purchased
directly from the trust are restricted securities that may not be resold except in transactions exempt from registration under the Securities Act of 1933 (the “Securities Act”) and state securities laws and any such transaction must be
approved by the Sponsor. In determining whether to grant approval, the Sponsor will specifically look at whether the conditions of Rule 144 under the Securities Act and any other applicable laws have been met. Any attempt to sell Shares without the
approval of the Sponsor in its sole discretion will be void ab initio. 
 Pursuant to Rule 144 under the Securities Act (“Rule
144”), once the Trust has been subject to the reporting requirements of Section 13 under the Exchange Act for a period of 90 days, a minimum six-month holding period will apply to all Shares
purchased from the Trust. 
 On a monthly basis, the Trust aggregates the Shares that have been held for the requisite holding period under
Rule 144 by non-affiliates of the Trust to assess whether the Rule 144 transfer restriction legends may be removed. Any Shares that qualify for the removal of the Rule 144 transfer restriction legends are
presented to outside counsel, who may instruct the Transfer Agent to remove the transfer restriction legends from the Shares, allowing the Shares to then be resold without restriction, including on OTCQX U.S. Premier marketplace. The outside counsel
requires that certain representations be made, providing that: 
  

	 	•	 the Shares subject to each sale have been held for the requisite holding period under Rule 144 by the selling
Shareholder; 

  

	 	•	 the Shareholder is the sole beneficial owner of the Shares; 

 

	 	•	 the Sponsor is aware of no circumstances in which the Shareholder would be considered an underwriter or engaged
in the distribution of securities for the Trust; 

  

	 	•	 none of the Shares are subject to any agreement granting any pledge, lien, mortgage, hypothecation, security
interest, charge, option or encumbrance; 

	 	•	 none of the identified selling Shareholders is an affiliate of the Sponsor; 

 

	 	•	 the Sponsor consents to the transfer of the Shares; and 

 

	 	•	 outside counsel and the Transfer Agent can rely on the representations. 

In addition, because the Trust Agreement prohibits the transfer or sale of Shares without the prior written consent of the Sponsor, the
Sponsor must provide a written consent that explicitly states that it irrevocably consents to the transfer and resale of the Shares. Once the transfer restriction legends have been removed from a Share and the Sponsor has provided its written
consent to the transfer of that Share, no consent of the Sponsor is required for future transfers of that particular Share. 
 Book-Entry Form 

Shares are held primarily in book-entry form by the Transfer Agent. The Sponsor or its delegate will direct the Transfer Agent to credit the
number of Creation Baskets to the applicable Authorized Participant. The Transfer Agent will issue Creation Baskets. Transfers will be made in accordance with standard securities industry practice. The Sponsor may cause the Trust to issue Shares in
certificated form in limited circumstances in its sole discretion. 
 Share Splits 

In its discretion, the Sponsor may direct the Transfer Agent to declare a split or reverse split in the number of Shares outstanding and to
make a corresponding change in the number of Shares constituting a Basket. For example, if the Sponsor believes that the per Share price in the secondary market for Shares has risen or fallen outside a desirable trading price range, it may declare
such a split or reverse split.
