Self-Regulatory Organizations; NYSE Arca, Inc.; Notice of Filing of Proposed Rule Change, as Modified by Amendment No. 1, To List and Trade Shares of the Grayscale Bitcoin Mini Trust Under NYSE Arca Rule 8.201-E, Commodity-Based Trust Shares

On May 28, 2024, NYSE Arca, Inc. (“NYSE Arca” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, a proposed rule change to list and trade shares (“Shares”) of the Grayscale Bitcoin Mini Trust under NYSE Arca Rule 8.201-E, Commodity-Based Trust Shares. On June 5, 2024, the Exchange filed Amendment No. 1, as described in Items I, II, and III below, which Items have been prepared by the Exchange. Amendment No. 1 replaced and superseded the proposed rule change in its entirety. The Commission is publishing this notice to solicit comments on the proposed rule change, as modified by Amendment No. 1, from interested persons.

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

The Exchange proposes to list and trade shares of the following under NYSE Arca Rule 8.201-E: Grayscale Bitcoin Mini Trust (BTC) (the “Trust”). This Amendment No. 1 to SR-NYSEARCA-2024-45 replaces SR-NYSEARCA2024-45 as originally filed and supersedes such filing in its entirety. The proposed rule change is available on the Exchange's website at www.nyse.com, at the principal office of the Exchange, and at the Commission's Public Reference Room.

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

In its filing with the Commission, the self-regulatory organization 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 those 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 parts of such statements.

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

1. Purpose

Under NYSE Arca Rule 8.201-E, the Exchange may propose to list and/or trade pursuant to unlisted trading privileges “Commodity-Based Trust Shares.” The Exchange proposes to list and trade shares (“Shares”) of the Trust pursuant to NYSE Arca Rule 8.201-E.

The sponsor of the Trust is Grayscale Investments, LLC (“Sponsor”), a Delaware limited liability company. The Sponsor is a wholly-owned subsidiary of Digital Currency Group, Inc. (“Digital Currency Group”). The trustee for the Trust is Delaware Trust Company (“Trustee”). The custodian for the Trust's Bitcoin is Coinbase Custody Trust Company, LLC (“Custodian”). The administrator and transfer agent of the Trust is BNY Mellon Asset Servicing, a division of The Bank of New York Mellon (the “Transfer Agent”). The distribution and marketing agent for the Trust will be Foreside Fund Services, LLC (the “Marketing Agent”). The index provider for the Trust is CoinDesk Indices, Inc. (the “Index Provider”).

The Trust is a Delaware statutory trust, formed on March 12, 2024, that operates pursuant to a trust agreement between the Sponsor and the Trustee (“Trust Agreement”). The Trust has no fixed termination date.

Operation of the Trust

According to the Registration Statement, the Trust's assets consist solely of Bitcoins.

Each Share represents a proportional interest, based on the total number of Shares outstanding, in the Trust's assets as determined by reference to the Index Price, less the Trust's expenses and other liabilities (which include accrued but unpaid fees and expenses). The Sponsor expects that the market price of the Shares will fluctuate over time in response to the market prices of Bitcoin. In addition, because the Shares reflect the estimated accrued but unpaid expenses of the Trust, the number of Bitcoins represented by a Share will gradually decrease over time as the Trust's Bitcoins are used to pay the Trust's expenses.

The activities of the Trust will be limited to (i) issuing “Baskets” (as defined below) in exchange for Bitcoins transferred to the Trust as consideration in connection with creations, (ii) transferring or selling Bitcoins as necessary to cover the Sponsor's Fee and/or certain Trust expenses, (iii) transferring Bitcoins in exchange for Baskets surrendered for redemption (subject to obtaining regulatory approval from the Commission and approval of the Sponsor), (iv) causing the Sponsor to sell Bitcoins on the termination of the Trust, and (v) engaging in all administrative and security procedures necessary to accomplish such activities in accordance with the provisions of the Trust Agreement, the Custodian Agreement, the Index License Agreement and the Participant Agreements (each as defined below).

The Trust will not be actively managed. It will not engage in any activities designed to obtain a profit from, or to ameliorate losses caused by, changes in the market prices of Bitcoins.

Investment Objective

According to the Registration Statement, the Trust's investment objective is for the value of the Shares (based on Bitcoin per Share) to reflect the value of the Bitcoins held by the Trust, determined by reference to the Index Price, less the Trust's expenses and other liabilities.

While an investment in the Shares is not a direct investment in Bitcoin, the Shares are designed to provide investors with a cost-effective and convenient way to gain investment exposure to Bitcoin. Generally speaking, a substantial direct investment in Bitcoin may require expensive and sometimes complicated arrangements in connection with the acquisition, security and safekeeping of the Bitcoin and may involve the payment of substantial fees to acquire such Bitcoin from third-party facilitators through cash payments of U.S. dollars. Because the value of the Shares is correlated with the value of Bitcoin held by the Trust, it is important to understand the investment attributes of, and the market for, Bitcoin.

The Trust uses the Index Price to calculate its “NAV,” which is the aggregate value, expressed in U.S. dollars, of the Trust's assets (other than U.S. dollars or other fiat currency), less the U.S. dollar value of the Trust's expenses and other liabilities calculated in the manner set forth under “Valuation of Bitcoin and Determination of NAV.” “NAV per Share” is calculated by dividing NAV by the number of Shares then outstanding.

Valuation of Bitcoin and Determination of NAV

The following is a description of the material terms of the Trust Agreement as it relates to valuation of the Trust's Bitcoin and the NAV calculations.

On each business day at 4:00 p.m., New York time, or as soon thereafter as practicable (the “Evaluation Time”), the Sponsor will evaluate the Bitcoins held by the Trust and calculate and publish the NAV of the Trust. To calculate the NAV, the Sponsor will:

1. Determine the Index Price as of such business day.

2. Multiply the Index Price by the Trust's aggregate number of Bitcoins owned by the Trust as of 4:00 p.m., New York time, on the immediately preceding day, less the aggregate number of Bitcoins payable as the accrued and unpaid Sponsor's Fee as of 4:00 p.m., New York time, on the immediately preceding day.

3. Add the U.S. dollar value of Bitcoins, calculated using the Index Price, receivable under pending creation orders, if any, determined by multiplying the number of the Baskets represented by such creation orders by the Basket Amount and then multiplying such product by the Index Price.

4. Subtract the U.S. dollar amount of accrued and unpaid Additional Trust Expenses, if any.

5. Subtract the U.S. dollar value of the Bitcoins, calculated using the Index Price, to be distributed under pending redemption orders, if any, determined by multiplying the number of Baskets to be redeemed represented by such redemption orders by the Basket Amount and then multiplying such product by the Index Price (the amount derived from steps 1 through 5 above, the “NAV Fee Basis Amount”).

6. Subtract the U.S. dollar amount of the Sponsor's Fee that accrues for such business day, as calculated based on the NAV Fee Basis Amount for such business day.

In the event that the Sponsor determines that the primary methodology used to determine the Index Price is not an appropriate basis for valuation of the Trust's Bitcoins, the Sponsor will utilize the cascading set of rules as described in “Determination of the Index Price When Index Price is Unavailable” below.

Bitcoin and the Bitcoin Network

According to the Registration Statement, Bitcoin is a digital asset that is created and transmitted through the operations of the peer-to-peer “Bitcoin Network,” a decentralized network of computers that operates on cryptographic protocols. No single entity owns or operates the Bitcoin Network, the infrastructure of which is collectively maintained by a decentralized user base. The Bitcoin Network allows people to exchange tokens of value, called Bitcoin, which are recorded on a public transaction ledger known as a Blockchain. Bitcoin can be used to pay for goods and services, or it can be converted to fiat currencies, such as the U.S. dollar, at rates determined on “Digital Asset Markets” that trade Bitcoin or in individual end-user-to-end-user transactions under a barter system.

The Bitcoin Network is decentralized in that it does not require governmental authorities or financial institution intermediaries to create, transmit or determine the value of Bitcoin. Rather, Bitcoin is created and allocated by the Bitcoin Network protocol through a “mining” process. The value of Bitcoin is determined by the supply of and demand for Bitcoin on the Digital Asset Markets or in private end-user-to-end-user transactions.

New Bitcoin are created and rewarded to the miners of a block in the Blockchain for verifying transactions. The Blockchain is effectively a decentralized database that includes all blocks that have been mined by miners and it is updated to include new blocks as they are solved. Each Bitcoin transaction is broadcast to the Bitcoin Network and, when included in a block, recorded in the Blockchain. As each new block records outstanding Bitcoin transactions, and outstanding transactions are settled and validated through such recording, the Blockchain represents a complete, transparent and unbroken history of all transactions of the Bitcoin Network.

Overview of the Bitcoin Network's Operations

In order to own, transfer or use Bitcoin directly on the Bitcoin Network (as opposed to through an intermediary, such as a custodian), a person generally must have internet access to connect to the Bitcoin Network. Bitcoin transactions may be made directly between end-users without the need for a third-party intermediary. To prevent the possibility of double-spending Bitcoin, a user must notify the Bitcoin Network of the transaction by broadcasting the transaction data to its network peers. The Bitcoin Network provides confirmation against double-spending by memorializing every transaction in the Blockchain, which is publicly accessible and transparent. This memorialization and verification against double-spending is accomplished through the Bitcoin Network mining process, which adds “blocks” of data, including recent transaction information, to the Blockchain.

Summary of a Bitcoin Transaction

Prior to engaging in Bitcoin transactions directly on the Bitcoin Network, a user generally must first install on its computer or mobile device a Bitcoin Network software program that will allow the user to generate a private and public key pair associated with a Bitcoin address, commonly referred to as a “wallet.” The Bitcoin Network software program and the Bitcoin address also enable the user to connect to the Bitcoin Network and transfer Bitcoin to, and receive Bitcoin from, other users.

Each Bitcoin Network address, or wallet, is associated with a unique “public key” and “private key” pair. To receive Bitcoin, the Bitcoin recipient must provide its public key to the party initiating the transfer. This activity is analogous to a recipient for a transaction in U.S. dollars providing a routing address in wire instructions to the payor so that cash may be wired to the recipient's account. The payor approves the transfer to the address provided by the recipient by “signing” a transaction that consists of the recipient's public key with the private key of the address from where the payor is transferring the Bitcoin. The recipient, however, does not make public or provide to the sender its related private key.

Neither the recipient nor the sender reveal their private keys in a transaction, because the private key authorizes transfer of the funds in that address to other users. Therefore, if a user loses his private key, the user may permanently lose access to the Bitcoin contained in the associated address. Likewise, Bitcoin is irretrievably lost if the private key associated with them is deleted and no backup has been made. When sending Bitcoin, a user's Bitcoin Network software program must validate the transaction with the associated private key. In addition, since every computation on the Bitcoin Network requires processing power, there is a transaction fee involved with the transfer that is paid by the payor. The resulting digitally validated transaction is sent by the user's Bitcoin Network software program to the Bitcoin Network miners to allow transaction confirmation.

Bitcoin Network miners record and confirm transactions when they mine and add blocks of information to the Blockchain. When a miner mines a block, it creates that block, which includes data relating to (i) newly submitted and accepted transactions; (ii) a reference to the prior block in the Bitcoin Blockchain; and (iii) the satisfaction of the consensus mechanism to mine the block. The miner becomes aware of outstanding, unrecorded transactions through the data packet transmission and distribution discussed above.

Upon the addition of a block included in the Blockchain, the Bitcoin Network software program of both the spending party and the receiving party will show confirmation of the transaction on the Blockchain and reflect an adjustment to the Bitcoin balance in each party's Bitcoin Network public key, completing the Bitcoin transaction. Once a transaction is confirmed on the Blockchain, it is irreversible.

Some Bitcoin transactions are conducted “off-blockchain” and are therefore not recorded in the Blockchain. Some “off-blockchain transactions” involve the transfer of control over, or ownership of, a specific digital wallet holding Bitcoin or the reallocation of ownership of certain Bitcoin in a pooled-ownership digital wallet, such as a digital wallet owned by a Digital Asset Trading Platform. In contrast to on-blockchain transactions, which are publicly recorded on the Blockchain, information and data regarding off-blockchain transactions are generally not publicly available. Therefore, off-blockchain transactions are not truly Bitcoin transactions in that they do not involve the transfer of transaction data on the Bitcoin Network and do not reflect a movement of Bitcoin between addresses recorded in the Blockchain. For these reasons, off-blockchain transactions are subject to risks, as any such transfer of Bitcoin ownership is not protected by the protocol behind the Bitcoin Network or recorded in, and validated through, the blockchain mechanism.

Limits on Bitcoin Supply

The supply of new Bitcoin is mathematically controlled so that the number of Bitcoin grows at a limited rate pursuant to a pre-set schedule. The number of Bitcoin awarded for solving a new block is automatically halved after every 210,000 blocks are added to the Blockchain. Currently, the fixed reward for solving a new block is 3.125 Bitcoin per block and this is expected to decrease by half to become 1.5625 Bitcoin after the next 210,000 blocks have entered the Bitcoin Network, which is expected to be mid-2028. This deliberately controlled rate of Bitcoin creation means that the number of Bitcoin in existence will increase at a controlled rate until the number of Bitcoin in existence reaches the pre-determined 21 million Bitcoin. As of March 31, 2024, approximately 19.7 million Bitcoins were outstanding and the date when the 21 million Bitcoin limitation will be reached is estimated to be the year 2140.

Custody of the Trust's Bitcoins

Digital assets and digital asset transactions are recorded and validated on blockchains, the public transaction ledgers of a digital asset network. Each digital asset blockchain serves as a record of ownership for all of the units of such digital asset, even in the case of certain privacy-preserving digital assets, where the transactions themselves are not publicly viewable. All digital assets recorded on a blockchain are associated with a public blockchain address, also referred to as a digital wallet. Digital assets held at a particular public blockchain address may be accessed and transferred using a corresponding private key.

Key Generation

Public addresses and their corresponding private keys are generated by the Custodian in secret key generation ceremonies at secure locations inside faraday cages, which are enclosures used to block electromagnetic fields and thus mitigate against attacks. The Custodian uses quantum random number generators to generate the public and private key pairs.

Once generated, private keys are encrypted, separated into “shards,” and then further encrypted. After the key generation ceremony, all materials used to generate private keys, including computers, are destroyed. All key generation ceremonies are performed offline. No party other than the Custodian has access to the private key shards of the Trust.

Key Storage

Private key shards are distributed geographically in secure vaults around the world, including in the United States. The locations of the secure vaults may change regularly and are kept confidential by the Custodian for security purposes.

The “Digital Asset Account” is a segregated custody account controlled and secured by the Custodian to store private keys, which allows for the transfer of ownership or control of the Trust's Bitcoins on the Trust's behalf. The Digital Asset Account uses offline storage, or “cold” storage, mechanisms to secure the Trust's private keys. The term cold storage refers to a safeguarding method by which the private keys corresponding to digital assets are disconnected and/or deleted entirely from the internet. Cold storage of private keys may involve keeping such keys on a non-networked (or “air-gapped”) computer or electronic device or storing the private keys on a storage device (for example, a USB thumb drive) or printed medium (for example, papyrus, paper or a metallic object). A digital wallet may receive deposits of digital assets but may not send digital assets without use of the digital assets' corresponding private keys. In order to send digital assets from a digital wallet in which the private keys are kept in cold storage, either the private keys must be retrieved from cold storage and entered into an online, or “hot,” digital asset software program to sign the transaction, or the unsigned transaction must be transferred to the cold server in which the private keys are held for signature by the private keys and then transferred back to the online digital asset software program. At that point, the user of the digital wallet can transfer its digital assets.

Security Procedures

The Custodian is the custodian of the Trust's private keys (which, as noted above, facilitate the transfer of ownership or control of the Trust's Bitcoins) in accordance with the terms and provisions of the custodian agreement by and between the Custodian, the Sponsor and the Trust (the “Custodian Agreement”). Transfers from the Digital Asset Account require certain security procedures, including, but not limited to, multiple encrypted private key shards, usernames, passwords and 2-step verification. Multiple private key shards held by the Custodian must be combined to reconstitute the private key to sign any transaction in order to transfer the Trust's assets. Private key shards are distributed geographically in secure vaults around the world, including in the United States.

As a result, if any one secure vault is ever compromised, this event will have no impact on the ability of the Trust to access its assets, other than a possible delay in operations, while one or more of the other secure vaults is used instead. These security procedures are intended to remove single points of failure in the protection of the Trust's assets.

Transfers of Bitcoins to the Digital Asset Account will be available to the Trust once processed on the Blockchain.

Subject to obtaining regulatory approval to operate a redemption program and authorization of the Sponsor, the process of accessing and withdrawing Bitcoins from the Trust to redeem a Basket by an Authorized Participant will follow the same general procedure as transferring Bitcoins to the Trust to create a Basket by an Authorized Participant, only in reverse.

The Sponsor will maintain ownership and control of the Trust's Bitcoin in a manner consistent with good delivery requirements for spot commodity transactions.

Bitcoin Value

Digital Asset Trading Platform Valuation

According to the Registration Statement, the value of Bitcoin is determined by the value that various market participants place on Bitcoin through their transactions. The most common means of determining the value of a Bitcoin is by surveying one or more Digital Asset Trading Platforms where Bitcoin is traded publicly ( e.g., Coinbase, Bitstamp, Crypto.com, Kraken, and LMAX Digital). Additionally, there are over-the-counter dealers or market makers that transact in Bitcoin.

Digital Asset Trading Platforms Public Market Data

On each online Digital Asset Trading Platforms, Bitcoin is traded with publicly disclosed valuations for each executed trade, measured by one or more fiat currencies such as the U.S. dollar or Euro. Over-the-counter dealers or market makers do not typically disclose their trade data.

As of March 31, 2024, the Digital Asset Trading Platforms included in the Index are Coinbase, Bitstamp, Kraken, LMAX Digital and Crypto.com. As further described below, the Sponsor and the Trust reasonably believe each of these Digital Asset Trading Platforms are in material compliance with applicable U.S. federal and state licensing requirements and maintain practices and policies designed to comply with know-your-customer (“KYC”), anti-money-laundering (“AML”) regulations.

Coinbase: A U.S.-based trading platform registered as a money services business (“MSB”) with the U.S. Department of Treasury's Financial Crimes Enforcement Network (“FinCEN”) and licensed as a virtual currency business under the New York State Department of Financial Services (“NYDFS”) BitLicense and as a money transmitter in various U.S. states.

Bitstamp: A U.K.-based trading platform registered as an MSB with FinCen and licensed as a virtual currency business under the NYDFS BitLicense and as a money transmitter in various U.S. states.

Kraken: A U.S.-based trading platform registered as an MSB with FinCEN and licensed as a money transmitter in various U.S. states. Kraken does not hold a BitLicense.

LMAX Digital: A U.K.-based trading platform registered as a broker with the Financial Conduct Authority. LMAX Digital does not hold a BitLicense.

Crypto.com: A Singapore-based trading platform registered as an MSB with FinCEN and licensed as a money transmitter in various U.S. states. Crypto.com does not hold a BitLicense.

Currently, there are several Digital Asset Trading Platforms operating worldwide, and online Digital Asset Trading Platforms represent a substantial percentage of Bitcoin buying and selling activity and provide the most data with respect to prevailing valuations of Bitcoins. These trading platforms include established trading platforms such as trading platforms included in the Index, which provide a number of options for buying and selling Bitcoins. The below table reflects the trading volume in Bitcoins and market share of the BTC-U.S. dollar trading pairs of each of the Digital Asset Trading Platforms included in the Index as of March 31, 2024 using data reported by the Index Provider from May 1, 2015 to March 31, 2024:

The domicile, regulation, and legal compliance of the Digital Asset Trading Platforms included in the Index varies. Information regarding each Digital Asset Trading Platform may be found, where available, on the websites for such Digital Asset Trading Platforms, among other places.

The Index and the Index Price

The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (i) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (ii) provide a real-time, volume-weighted fair value of Bitcoin and (iii) appropriately handle and adjust for non-market related events.

The Index Price is determined by the Index Provider through a process in which trade data is cleansed and compiled in such a manner as to algorithmically reduce the impact of anomalistic or manipulative trading. This is accomplished by adjusting the weight of each data input based on price deviation relative to the observable set, as well as recent and long-term trading volume at each venue relative to the observable set.

The value of the Index is calculated and disseminated on a 24-hour basis and will be available on a continuous basis at https://www.coindesk.com/indices.

Constituent Trading Platform Selection

According to the Registration Statement, the Digital Asset Trading Platforms that are included in the Index are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions (“IOSCO”) principles for financial benchmarks. For a trading platform to become a Digital Asset Trading Platform included in the Index (a “Constituent Trading Platform”), it must satisfy the criteria listed below (the “Inclusion Criteria”):

• Sufficient USD liquidity relative to the size of the listed assets;
• No evidence in the past 12 months of trading restrictions on individuals or entities that would otherwise meet the trading platform's eligibility requirements to trade;
• No evidence in the past 12 months of undisclosed restrictions on deposits or withdrawals from user accounts;
• Real-time price discovery;
• Limited or no capital controls;

• Transparent ownership including a publicly-owned ownership entity;
• Publicly available language and policies addressing legal and regulatory compliance in the U.S., including KYC (Know Your Customer), AML (Anti-Money Laundering) and other policies designed to comply with relevant regulations that might apply to it;
• Be a U.S.-domiciled trading platform or a non-U.S. domiciled trading platform that is able to service U.S. investors;
• Offer programmatic spot trading of the trading pair, and reliably publish trade prices and volumes on a real-time basis through Rest and Websocket APIs.

A Digital Asset Trading Platform is removed from the Constituent Trading Platforms when it no longer satisfies the Inclusion Criteria. The Index Provider does not currently include data from non-Digital Asset Trading Platforms (or over-the-counter markets) or derivatives platforms among the Constituent Trading Platforms. According to the Registration Statement, over-the-counter data is not currently included because of the potential for trades to include a significant premium or discount paid for larger liquidity, which creates an uneven comparison relative to more active markets. There is also a higher potential for over-the-counter transactions to not be arms-length, and thus not be representative of a true market price. Bitcoin derivative markets data, including Bitcoin futures markets and perpetuals markets data, are also not currently included as the markets remain relatively thin. The Index Provider will consider IOSCO principles for financial benchmarks and the management of trading venues of Bitcoin derivatives and the aforementioned Inclusion Criteria when considering inclusion of over-the-counter or derivative platform data in the future.

The Index Provider and the Sponsor have entered into the index license agreement (as amended, the “Index License Agreement”), governing the Sponsor's use of the Index Price. Pursuant to the terms of the Index License Agreement, the Index Provider may adjust the calculation methodology for the Index Price without notice to, or consent of, the Trust or its shareholders. The Index Provider may decide to change the calculation methodology to maintain the integrity of the Index Price calculation should it identify or become aware of previously unknown variables or issues with the existing methodology that it believes could materially impact its performance and/or reliability. The Index Provider has sole discretion over the determination of Index Price and may change the methodologies for determining the Index Price from time to time. Shareholders will be notified of any material changes to the calculation methodology or the Index Price in the Trust's current reports and will be notified of all other changes that the Sponsor considers significant in the Trust's periodic or current reports. The Trust will determine the materiality of any changes to the Index Price on a case-by-case basis, in consultation with external counsel.

The Index Provider may change the trading venues that are used to calculate the Index or otherwise change the way in which the Index is calculated at any time. For example, the Index Provider has scheduled quarterly reviews in which it may add or remove Constituent Trading Platforms that satisfy or fail the Inclusion Criteria. The Index Provider does not have any obligation to consider the interests of the Sponsor, the Trust, the shareholders, or anyone else in connection with such changes. Although the Index Provider is not required to publicize or explain the changes or to alert the Sponsor to such changes, it has historically notified the Trust (and other subscribers to the Index) of any material changes to the Constituent Trading Platforms, including any additions or removals, contemporaneous with its issuance of press releases in connection with the same. The Sponsor will notify investors of any such material event by filing a current report on Form 8-K. Although the Index methodology is designed to operate without any manual intervention, rare events would justify manual intervention. Intervention of this kind would be in response to non-market-related events, such as the halting of deposits or withdrawals of funds on a Digital Asset Trading Platform, the unannounced closure of operations on a Digital Asset Trading Platform, insolvency or the compromise of user funds. In the event that such an intervention is necessary, the Index Provider would issue a public announcement through its website, API and other established communication channels with its clients.

Determination of the Index Price

The Index applies an algorithm to the price of Bitcoin on the Constituent Trading Platforms calculated on a per second basis over a 24-hour period. The Index's algorithm is expected to reflect a four-pronged methodology to calculate the Index Price from the Constituent Trading Platforms:

• Volume Weighting: Constituent Trading Platforms with greater liquidity receive a higher weighting in the Index, increasing the ability to execute against ( i.e., replicate) the Index in the underlying spot markets.
• Price-Variance Weighting: The Index Price reflects data points that are discretely weighted in proportion to their variance from the rest of the Constituent Trading Platforms. As the price at a particular trading platform diverges from the prices at the rest of the Constituent Trading Platforms, its weight in the Index Price consequently decreases.
• Inactivity Adjustment: The Index Price algorithm penalizes stale activity from any given Constituent Trading Platform. When a Constituent Trading Platform does not have recent trading data, its weighting in the Index Price is gradually reduced until it is de-weighted entirely. Similarly, once trading activity at a Constituent Trading Platform resumes, the corresponding weighting for that Constituent Trading Platform is gradually increased until it reaches the appropriate level.
• Manipulation Resistance: In order to mitigate the effects of wash trading and order book spoofing, the Index only includes executed trades in its calculation. Additionally, the Index only includes Constituent Trading Platforms that charge trading fees to its users in order to attach a real, quantifiable cost to any manipulation attempts.

The Index Provider re-evaluates the weighting algorithm on a periodic basis, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances and does not make the exact methodology to calculate the Index Price publicly available. Nonetheless, the Sponsor believes that, the Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms.

The Sponsor believes the Index Provider's selection process for Constituent Trading Platforms as well as the methodology of the Index Price's algorithm provides a more accurate picture of Bitcoin price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of Bitcoin prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the Bitcoin spot market. By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.

If the Index Price becomes unavailable, or if the Sponsor determines in good faith that such Index Price does not reflect an accurate price for Bitcoin, then the Sponsor will, on a best efforts basis, contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact such Index Price remains unavailable or the Sponsor continues to believe in good faith that such Index Price does not reflect an accurate price for the relevant digital asset, then the Sponsor will employ a cascading set of rules to determine the Index Price, as described below in “Determination of the Index Price When Index Price is Unavailable.”

The Trust values its Bitcoin for operational purposes by reference to the Index Price. The Index Price is the value of a Bitcoin as represented by the Index, calculated at 4:00 p.m., New York time, on each business day.

Illustrative Example

For the purposes of illustration, outlined below are examples of how the attributes that impact weighting and adjustments in the aforementioned methodology may be utilized to generate the Index Price for a digital asset. For purposes of this illustrative example only, assume that the Constituent Trading Platforms used to calculate the Index Price for a digital asset are Coinbase, Kraken, LMAX Digital and Bitstamp.

The Index Price algorithm, as described above, accounts for manipulation at the outset by only including data from executed trades on Constituent Trading Platforms that charge trading fees. Then, the below-listed elements may impact the weighting of the Constituent Trading Platforms on the Index Price as follows:

• Volume Weighting: Each Constituent Trading Platform will be weighted to appropriately reflect the trading volume share of the Constituent Trading Platform relative to all the Constituent Trading Platforms during this same period. For example, an average hourly weighting of 67.06%, 14.57%, 11.88% and 6.49% for Coinbase, Kraken, LMAX Digital and Bitstamp, respectively, would represent each Constituent Trading Platform's share of trading volume during the same period.
• Inactivity Adjustment: Assume that a Constituent Trading Platform represented a 14% weighting on the Index Price of the digital asset, which is based on the per-second calculations of its trading volume and price-variance relative to the cohort of Constituent Trading Platforms included in such Index, and then went offline for approximately two hours. The index algorithm would automatically recognize inactivity and start de-weighting the Constituent Trading Platform at the 3-minute mark and continue to do so over a 7-minute period until its influence was effectively zero, 10 minutes after becoming inactive. As soon as trading activity resumed at the Constituent Trading Platform, the index algorithm would re-weight it to the appropriate weighting based on trading volume and price-variance relative to the cohort of Constituent Trading Platforms included in the Index. Due to the period of inactivity, it would re-weight the Constituent Trading Platform activity to a weight lower than its original weighting—for example, to 12%.
• Price-Variance Weighting: Assume that for a one-hour period, the digital asset's execution prices on one Constituent Trading Platform were trading more than 7% higher than the average execution prices on another Constituent Trading Platform. The algorithm will automatically detect the anomaly and reduce that specific Constituent Trading Platform's weighting to 0% for that one-hour period, ensuring a reliable spot reference unaffected by the localized event.

Determination of the Index Price When Index Price Is Unavailable

The Sponsor uses the following cascading set of rules to calculate the Index Price when the Index Price is unavailable. For the avoidance of doubt, the Sponsor will employ the below rules sequentially and in the order as presented below, should one or more specific rule(s) fail.

1. Index Price = The price set by the Index as of 4:00 p.m., New York time, on the valuation date. If the Index becomes unavailable, or if the Sponsor determines in good faith that the Index does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact the Index remains unavailable or the Sponsor continues to believe in good faith that the Index does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

2. Index Price = The price set by Coin Metrics Real-Time Rate (the “Secondary Index”) as of 4:00 p.m., New York time, on the valuation date (the “Secondary Index Price”). The Secondary Index Price is a real-time reference rate price, calculated using trade data from constituent markets selected by Coin Metrics (the “Secondary Index Provider”). The Secondary Index Price is calculated by applying weighted-median techniques to such trade data where half the weight is derived from the trading volume on each constituent market and half is derived from inverse price variance, where a constituent market with high price variance as a result of outliers or market anomalies compared to other constituent markets is assigned a smaller weight. If the Secondary Index becomes unavailable, or if the Sponsor determines in good faith that the Secondary Index does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Secondary Index Provider to obtain the Secondary Index Price directly from the Secondary Index Provider. If after such contact the Secondary Index remains unavailable or the Sponsor continues to believe in good faith that the Secondary Index does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

3. Index Price = The price set by the Trust's principal market (as defined in the Registration Statement) (the “Tertiary Pricing Option”) as of 4:00 p.m., New York time, on the valuation date. The Tertiary Pricing Option is a spot price derived from the principal market's public data feed that is believed to be consistently publishing pricing information as of 4:00 p.m., New York time, and is provided to the Sponsor via an application programming interface. If the Tertiary Pricing Option becomes unavailable, or if the Sponsor determines in good faith that the Tertiary Pricing Option does not reflect an accurate price, then the Sponsor will, on a best efforts basis, contact the Tertiary Pricing Provider to obtain the Tertiary Pricing Option directly from the Tertiary Pricing Provider. If after such contact the Tertiary Pricing Option remains unavailable after such contact or the Sponsor continues to believe in good faith that the Tertiary Pricing Option does not reflect an accurate price, then the Sponsor will employ the next rule to determine the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

4. Index Price = The Sponsor will use its best judgment to determine a good faith estimate of the Index Price. There are no predefined criteria to make a good faith assessment and it will be made by the Sponsor in its sole discretion.

In the event of a fork, the Index Provider may calculate the Index Price based on a digital asset that the Sponsor does not believe to be an appropriate asset of the Trust ( i.e., a digital asset other than Bitcoin). In this event, the Sponsor has full discretion to use a different index provider or calculate the Index Price itself using its best judgment. In such an event, the Exchange will submit a proposed rule filing to contemplate the assets that would subsequently be held by the Trust.

The Sponsor may, in its sole discretion, select a different index provider, select a different index price provided by the Index Provider, calculate the Index Price by using the cascading set of rules set forth above, or change the cascading set of rules set forth above at any time.

The Structure and Operation of the Trust Protects Investors and Satisfies Commission Requirements for Bitcoin-Based Exchange Traded Products

On January 10, 2024, the Commission approved the listing and trading of shares of Grayscale Bitcoin Trust (BTC) and Bitwise Bitcoin ETF under NYSE Arca Rule 8.201-E (Commodity-Based Trust Shares); the Hashdex Bitcoin ETF under NYSE Arca Rule 8.500-E (Trust Units); the iShares Bitcoin Trust and Valkyrie Bitcoin Fund under Nasdaq Rule 5711(d) (Commodity-Based Trust Shares); and the ARK 21Shares Bitcoin ETF, Invesco Galaxy Bitcoin ETF, VanEck Bitcoin Trust, the WisdomTree Bitcoin Fund, Fidelity Wise Origin Bitcoin Fund, and Franklin Bitcoin ETF under BZX Rule 14.11(e)(4) (Commodity-Based Trust Shares) (collectively, the “Bitcoin ETPs”). In the Bitcoin ETP Approval Order, the Commission found that the proposed rule changes to list the Bitcoin ETPs demonstrated that there were “sufficient `other means' of preventing fraud and manipulation,” including that:

[B]ased on the record before the Commission and the improved quality of the correlation analysis in the record, including the Commission's own analysis, the Commission is able to conclude that fraud or manipulation that impacts prices in spot bitcoin markets would likely similarly impact CME bitcoin futures prices. And because the CME's surveillance can assist in detecting those impacts on CME bitcoin futures prices, the Exchanges' comprehensive surveillance-sharing agreement with the CME—a U.S. regulated market whose bitcoin futures market is consistently highly correlated to spot bitcoin, albeit not of “significant size” related to spot bitcoin—can be reasonably expected to assist in surveilling for fraudulent and manipulative acts and practices in the specific context of the [Bitcoin ETPs].

The Trust is structured and will operate in a manner materially the same as the Bitcoin ETPs. Accordingly, the Sponsor believes that, for the reasons set forth in the Bitcoin ETP Approval Order, listing and trading Shares of the Trust would be consistent with the requirements of the Act.

Creation and Redemption of Shares

Authorized Participants may submit orders to create or redeem Shares under procedures for “Cash Orders.”

The Authorized Participants will deliver only cash to create Shares and will receive only cash when redeeming Shares. Further, Authorized Participants will not directly or indirectly purchase, hold, deliver, or receive Bitcoin as part of the creation or redemption process or otherwise direct the Trust or a third party with respect to purchasing, holding, delivering, or receiving Bitcoin as part of the creation or redemption process.

The Trust will create Shares by receiving Bitcoin from a third party that is not the Authorized Participant and the Trust, or an affiliate of the Trust (and in any event not the Authorized Participant), is responsible for selecting the third party to deliver the Bitcoin. Further, the third party will not be acting as an agent of the Authorized Participant with respect to the delivery of the Bitcoin to the Trust or acting at the direction of the Authorized Participant with respect to the delivery of the Bitcoin to the Trust. The Trust will redeem Shares by delivering Bitcoin to a third party that is not the Authorized Participant and the Trust, or an affiliate of the Trust (and in any event not the Authorized Participant), is responsible for selecting the third party to receive the Bitcoin. Further, the third party will not be acting as an agent of the Authorized Participant with respect to the receipt of the Bitcoin from the Trust or acting at the direction of the Authorized Participant with respect to the receipt of the Bitcoin from the Trust.

Cash Orders are made through the participation of a Liquidity Provider who obtains or receives Bitcoin in exchange for cash, and are facilitated by the Transfer Agent and Grayscale Investments, LLC, acting in its capacity as the Liquidity Engager. Liquidity Providers are not party to the Participant Agreements and are engaged separately by the Liquidity Engager.

According to the Registration Statement, the Trust creates Baskets (as described below) of Shares only upon receipt of Bitcoins and redeems Shares only by distributing Bitcoins. “Authorized Participants” are the only persons that may place orders to create and redeem Baskets. Each Authorized Participant must (i) be a registered broker-dealer and (ii) enter into an agreement with the Sponsor and Transfer Agent that provides the procedures for the creation and redemption of Baskets and for the delivery of Bitcoins required for the creation and redemption of Baskets via a Liquidity Provider (each, a “Participant Agreement”). An Authorized Participant may act for its own account or as agent for broker-dealers, custodians and other securities market participants that wish to create or redeem Baskets. Shareholders who are not Authorized Participants will only be able to create or redeem their Shares through an Authorized Participant.

The Trust issues Shares to and redeems Shares from Authorized Participants on an ongoing basis, but only in one or more “Baskets” (with a Basket being a block of 10,000 Shares). The Trust will not issue fractions of a Basket.

The creation and redemption of Baskets will be made only in exchange for the delivery to the Trust, or the distribution by the Trust, of the number of whole and fractional Bitcoins represented by each Basket being created or redeemed, which is determined by dividing (x) the number of Bitcoins owned by the Trust at 4:00 p.m., New York time, on the trade date of a creation or redemption order, after deducting the number of Bitcoins representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust (converted using the Index Price at such time, and carried to the eighth decimal place), by (y) the number of Shares outstanding at such time (with the quotient so obtained calculated to one one-hundred-millionth of one Bitcoin ( i.e., carried to the eighth decimal place)), and multiplying such quotient by 10,000 (the “Basket Amount”). The U.S. dollar value of a Basket is calculated by multiplying the Basket Amount by the Index Price as of the trade date (the “Basket NAV”). The Basket NAV multiplied by the number of Baskets being created or redeemed is referred to as the “Total Basket NAV.” All questions as to the calculation of the Basket Amount will be conclusively determined by the Sponsor and will be final and binding on all persons interested in the Trust. The number of Bitcoins represented by a Share will gradually decrease over time as the Trust's Bitcoins are used to pay the Trust's expenses.

The creation of Baskets requires the delivery by the Authorized Participant of the Total Basket Amount and the redemption of Baskets requires the distribution to the Authorized Participant of the Total Basket Amount.

Although the Trust creates Baskets only upon the receipt of Bitcoins, and redeems Baskets only by distributing Bitcoins, an Authorized Participant will submit Cash Orders, pursuant to which the Authorized Participant will deposit cash with, or accept cash from, the Transfer Agent in connection with the creation and redemption of Baskets.

Cash Orders will be facilitated by the Transfer Agent and Liquidity Engager, acting other than in its capacity as Sponsor. On an order-by-order basis, the Liquidity Engager will engage one or more Liquidity Providers to obtain or receive Bitcoin in exchange for cash in connection with such order, as described in more detail below.

Unless the Sponsor requires that a Cash Order be effected at actual execution prices (an “Actual Execution Cash Order”), each Authorized Participant that submits a Cash Order to create or redeem Baskets (a “Variable Fee Cash Order”) will pay a fee (the “Variable Fee”) based on the Total Basket NAV, and any price differential of Bitcoins between the trade date and the settlement date will be borne solely by the Liquidity Provider until such Bitcoins have been received or liquidated by the Trust. The Variable Fee is intended to cover all of a Liquidity Provider's expenses in connection with the creation or redemption order, including any Bitcoin trading platform fees that the Liquidity Provider incurs in connection with buying or selling Bitcoins. The amount may be changed by the Sponsor in its sole discretion at any time, and Liquidity Providers will communicate to the Sponsor in advance the Variable Fee they would be willing to accept in connection with a Variable Fee Cash Order, based on market conditions and other factors existing at the time of such Variable Fee Cash Order.

Alternatively, the Sponsor may require that a Cash Order be effected as an Actual Execution Cash Order, in its sole discretion based on market conditions and other factors existing at the time of such Cash Order, and under such circumstances, any price differential of Bitcoins between the trade date and the settlement date will be borne solely by the Authorized Participant until such Bitcoins have been received or liquidated by the Trust.

In the case of creations, to transfer the Total Basket Amount to the Trust's Digital Asset Account, the Liquidity Provider will transfer Bitcoin to one of the public key addresses associated with the Digital Asset Account and as provided by the Sponsor. In the case of redemptions, the same procedure is conducted, but in reverse, using the public key addresses associated with the wallet of the Liquidity Provider and as provided by such party. All such transactions will be conducted on the Blockchain and parties acknowledge and agree that such transfers may be irreversible if done incorrectly.

Authorized Participants do not pay a transaction fee to the Trust in connection with the creation or redemption of Baskets, but there may be transaction fees associated with the validation of the transfer of Bitcoins by the Bitcoin Network, which will be paid by the Custodian in the case of redemptions and the Authorized Participant or the Liquidity Provider in the case of creations. Service providers may charge Authorized Participants administrative fees for order placement and other services related to creation of Baskets. As discussed above, Authorized Participants will also pay the Variable Fee in connection with Variable Fee Cash Orders. Under certain circumstances Authorized Participants may also be required to deposit additional cash in the Cash Account, or be entitled to receive excess cash from the Cash Account, in connection with creations and redemptions pursuant to Actual Execution Cash Orders. Authorized Participants will receive no fees, commissions or other form of compensation or inducement of any kind from either the Sponsor or the Trust and no such person has any obligation or responsibility to the Sponsor or the Trust to effect any sale or resale of Shares.

The following is a summary of the procedures for the creation and redemption of Baskets.

Creation Procedures

On any business day, an Authorized Participant may place an order with the Transfer Agent to create one or more Baskets.

Cash Orders for creation must be placed with the Transfer Agent no later than 1:59:59 p.m., New York time.

The Sponsor may in its sole discretion limit the number of Shares created pursuant to Cash Orders on any specified day without notice to the Authorized Participants and may direct the Marketing Agent to reject any Cash Orders in excess of such capped amount. In exercising its discretion to limit the number of Shares created pursuant to Cash Orders, the Sponsor expects to take into consideration a number of factors, including the availability of Liquidity Providers to facilitate Cash Orders and the cost of processing Cash Orders.

Creations under Cash Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day. Before a creation order is placed, the Sponsor determines if such creation order will be a Variable Fee Cash Order or an Actual Execution Cash Order, which determination is communicated to the Authorized Participant.

Redemption Procedures

The procedures by which an Authorized Participant can redeem one or more Baskets mirror the procedures for the creation of Baskets. On any business day, an Authorized Participant may place a redemption order specifying the number of Baskets to be redeemed.

The redemption of Shares pursuant to Cash Orders will only take place if approved by the Sponsor in writing, in its sole discretion and on a case-by-case basis. In exercising its discretion to approve the redemption of Shares pursuant to Cash Orders, the Sponsor expects to take into consideration a number of factors, including the availability of Liquidity Providers to facilitate Cash Orders and the cost of processing Cash Orders

Cash Orders for redemption must be placed no later than 1:59:59 p.m., New York time on each business day. The Authorized Participants may only redeem Baskets and cannot redeem any Shares in an amount less than a Basket.

Redemptions under Cash Orders will take place as follows, where “T” is the trade date and each day in the sequence must be a business day. Before a redemption order is placed, the Sponsor determines if such redemption order will be a Variable Fee Cash Order or an Actual Execution Cash Order, which determination is communicated to the Authorized Participant.

Suspension or Rejection of Orders and Total Basket Amount

The creation or redemption of Shares may be suspended generally, or refused with respect to particular requested creations or redemptions, during any period when the transfer books of the Transfer Agent are closed or if circumstances outside the control of the Sponsor or its delegates make it for all practicable purposes not feasible to process creation orders or redemption orders or for any other reason at any time or from time to time. The Transfer Agent may reject an order or, after accepting an order, may cancel such order if: (i) such order is not presented in proper form as described in the Participant Agreement, (ii) the transfer of the Total Basket Amount comes from an account other than a Bitcoin wallet address that is known to the Custodian as belonging to a Liquidity Provider or (iii) the fulfillment of the order, in the opinion of counsel, might be unlawful, among other reasons. None of the Sponsor or its delegates will be liable for the suspension, rejection or acceptance of any creation order or redemption order.

Availability of Information

The Trust's website ( https://grayscale.com/crypto-products/grayscale-bitcoin-trust/ ) will include quantitative information on a per Share basis updated on a daily basis, including, (i) the current NAV per Share daily and the prior business day's NAV per Share and the reported closing price of the Shares; (ii) the mid-point of the bid-ask price as of the time the NAV per Share is calculated (“Bid-Ask Price”) and a calculation of the premium or discount of such price against such NAV per Share; and (iii) data in chart format displaying the frequency distribution of discounts and premiums of the daily Bid-Ask Price against the NAV, within appropriate ranges, for each of the four previous calendar quarters (or for as long as the Trust has been trading as an ETP if shorter). In addition, on each business day the Trust's website will provide pricing information for the Shares.

One or more major market data vendors, will provide an intra-day 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 Core Trading Session (9:30 a.m. to 4:00 p.m., E.T.). The IIV will be calculated using the same methodology as the NAV per Share of the Trust (as described above), specifically by using the prior day's closing NAV per Share as a base and updating that value during the NYSE Arca Core Trading Session based on the value of the Index during the trading day.

The IIV disseminated during the NYSE Arca Core Trading Session should not be viewed as an actual real-time update of the NAV per Share, 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 NYSE Arca Core Trading Session by one or more major market data vendors. In addition, the IIV will be available through on-line information services.

The NAV for the Trust will be calculated by the Sponsor once a day and will be disseminated daily to all market participants at the same time. To the extent that the Sponsor has utilized the cascading set of rules described in “Index Price” above, the Trust's website will note the valuation methodology used and the price per Bitcoin resulting from such calculation. 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 will be widely disseminated through a variety of major market data vendors, including Bloomberg and Reuters. In addition, real-time price (and volume) data for Bitcoin is available by subscription from Reuters and Bloomberg. The spot price of Bitcoin is available on a 24-hour basis from major market data vendors, including Bloomberg and Reuters. Information relating to trading, including price and volume information, in Bitcoin will be available from major market data vendors and from the trading platforms on which Bitcoin is traded. The normal trading hours for Digital Asset Trading Platforms are 24-hours per day, 365-days per year.

On each business day, the Sponsor will publish the Index Price, the Trust's NAV, and the NAV per Share on the Trust's website as soon as practicable after its determination. If the NAV and NAV per Share have been calculated using a price per Bitcoin other than the Index Price for such Evaluation Time, the publication on the Trust's website will note the valuation methodology used and the price per Bitcoin resulting from such calculation.

The Trust will provide website disclosure of its NAV and NAV per Share daily. The website disclosure of the Trust's NAV and NAV per Share will occur at the same time as the disclosure by the Sponsor of the NAV and NAV per Share to Authorized Participants so that all market participants are provided such portfolio information at the same time. Therefore, the same portfolio information will be provided on the public website as well as in electronic files provided to Authorized Participants. Accordingly, each investor will have access to the current NAV and NAV per Share of the Trust through the Trust's website, as well as from one or more major market data vendors.

The value of the Index, as well as additional information regarding the Index, will be available on a continuous basis at https://www.coindesk.com/indices.

Information regarding market price and trading volume of the Shares will be continually available on a real-time basis throughout the day on brokers' computer screens and other electronic services.

Information regarding the previous day's closing price and trading volume information for the Shares will be published daily in the financial section of newspapers.

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. Shares will trade on the NYSE Arca Marketplace from 4:00 a.m. to 8:00 p.m., E.T. in accordance with NYSE Arca Rule 7.34-E (Early, Core, and Late Trading Sessions). The Exchange has appropriate rules to facilitate transactions in the Shares during all trading sessions. As provided in NYSE Arca Rule 7.6-E, the minimum price variation (“MPV”) for quoting and entry of orders in equity securities traded on the NYSE Arca Marketplace is $0.01, with the exception of securities that are priced less than $1.00, for which the MPV for order entry is $0.0001.

The Shares will conform to the initial and continued listing criteria under NYSE Arca Rule 8.201-E. The trading of the Shares will be subject to NYSE Arca Rule 8.201-E(g), which sets forth certain restrictions on Equity Trading Permit Holders (“ETP Holders”) acting as registered Market Makers in Commodity-Based Trust Shares to facilitate surveillance. The Exchange represents that, for initial and continued listing, the Trust will be in compliance with Rule 10A-3 under the Act, as provided by NYSE Arca Rule 5.3-E. A minimum of 100,000 Shares of the Trust will be outstanding at the commencement of trading on 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 of the Trust. Trading in Shares of the Trust will be halted if the circuit breaker parameters in NYSE Arca Rule 7.12-E have been reached. Trading also may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Shares inadvisable.

The Exchange may halt trading during the day in which an interruption to the dissemination of the IIV or the value of the Index occurs. If the interruption to the dissemination of the IIV or the value of the Index persists past the trading day in which it occurred, the Exchange will halt trading no later than the beginning of the trading day following the interruption. In addition, if the Exchange becomes aware that the NAV per Share is not disseminated to all market participants at the same time, it will halt trading in the Shares until such time as the NAV per Share is available to all market participants.

Surveillance

The Exchange represents that trading in the Shares of the Trust will be subject to the existing trading surveillances administered by the Exchange, as well as cross-market surveillances administered by FINRA on behalf of the Exchange, which are designed to detect violations of Exchange rules and applicable federal securities laws. The Exchange represents that these procedures are adequate to properly monitor Exchange trading of the Shares in all trading sessions and to deter and detect violations of Exchange rules and federal securities laws applicable to trading on the Exchange.

The surveillances referred to above generally focus on detecting securities trading outside their normal patterns, which could be indicative of manipulative or other violative activity. When such situations are detected, surveillance analysis follows and investigations are opened, where appropriate, to review the behavior of all relevant parties for all relevant trading violations.

The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares and Bitcoin derivatives from such markets and other entities. In addition, the Exchange may obtain information regarding trading in the Shares and Bitcoin derivatives from markets and other entities that are members of ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement (“CSSA”). The Exchange is also able to obtain information regarding trading in the Shares and any underlying Bitcoin, Bitcoin futures contracts, options on Bitcoin futures, or any other Bitcoin derivative in connection with ETP Holders' proprietary trades, or customer trades effected through ETP Holders on any relevant market.

Under NYSE Arca Rule 8.201-E(g), an ETP Holder acting as a registered Market Maker in the Shares is required to provide the Exchange with information relating to its accounts for trading in any underlying commodity, related futures or options on futures, or any other related derivatives. Commentary .04 of NYSE Arca Rule 11.3-E requires an ETP Holder acting as a registered Market Maker, and its affiliates, in the Shares to establish, maintain and enforce written policies and procedures reasonably designed to prevent the misuse of any material nonpublic information with respect to such products, any components of the related products, any physical asset or commodity underlying the product, applicable currencies, underlying indexes, related futures or options on futures, and any related derivative instruments (including the Shares). As a general matter, the Exchange has regulatory jurisdiction over its ETP Holders and their associated persons, which include any person or entity controlling an ETP Holder. To the extent the Exchange may be found to lack jurisdiction over a subsidiary or affiliate of an ETP Holder that does business only in commodities or futures contracts and that subsidiary or affiliate is a member of another regulatory organization, the Exchange could obtain information regarding the activities of such subsidiary or affiliate through a surveillance sharing agreement with that regulatory organization.

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

All statements and representations made in this filing regarding (a) the description of the index, portfolio or reference asset, (b) limitations on index or portfolio holdings or reference assets, or (c) the applicability of Exchange listing rules specified in this rule filing shall constitute continued listing requirements for listing the Shares on the Exchange.

The Sponsor has represented to the Exchange that it will advise the Exchange of any failure by the Trust to comply with the continued listing requirements, and, pursuant to its obligations under Section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If the Trust is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Rule 5.5-E(m).

Information Bulletin

Prior to the commencement of trading, the Exchange will inform its ETP Holders in an “Information Bulletin” of the special characteristics and risks associated with trading the Shares. Specifically, the Information Bulletin will discuss the following: (1) the procedures for creations of Shares in Baskets; (2) NYSE Arca Rule 9.2-E(a), which imposes a duty of due diligence on its ETP Holders to learn the essential facts relating to every customer prior to trading the Shares; (3) information regarding how the value of the Index and NAV are disseminated; (4) the possibility that trading spreads and the resulting premium or discount on the Shares may widen during the Opening and Late Trading Sessions, when an updated IIV will not be calculated or publicly disseminated; (5) the requirement that members deliver a prospectus to investors purchasing newly issued Shares prior to or concurrently with the confirmation of a transaction and (6) trading information.

In addition, the Information Bulletin will reference that the Trust is subject to various fees and expenses as described in the Registration Statement. The Information Bulletin will disclose that information about the Shares of the Trust is publicly available on the Trust's website. The Information Bulletin will also reference the fact that there is no regulated source of last sale information regarding Bitcoin, that the Commission has no jurisdiction over the trading of Bitcoin as a commodity, and that the CFTC has regulatory jurisdiction over the trading of CME Bitcoin futures contracts and options on CME Bitcoin futures contracts.

The Information Bulletin will also discuss any relief, if granted, by the Commission or the staff from any rules under the Act.

2. Statutory Basis

The basis under the Act for this proposed rule change is the requirement under Section 6(b)(5) that an exchange have rules that are designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to, and perfect the mechanism of a free and open market and, in general, to protect investors and the public interest.

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 and traded on the Exchange pursuant to the initial and continued listing criteria in NYSE Arca Rule 8.201-E. The Exchange has in place surveillance procedures that are adequate to properly monitor trading in the Shares in all trading sessions and to deter and detect violations of Exchange rules and applicable federal securities laws. The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares with other markets that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares and Bitcoin derivatives from such markets. In addition, the Exchange may obtain information regarding trading in the Shares and Bitcoin derivatives from markets that are members of ISG or with which the Exchange has in place a CSSA. Also, pursuant to NYSE Arca Rule 8.201-E(g), the Exchange is able to obtain information regarding Market Maker accounts for trading in the Shares and the underlying Bitcoin or any Bitcoin derivative through ETP Holders acting as registered Market Makers, in connection with such ETP Holders' proprietary trades which they effect on any relevant market.

The proposed rule change is also designed to prevent fraudulent and manipulative acts and practices because the Trust is structured similarly to and will operate in materially the same manner as the Bitcoin ETPs previously approved by the Commission. The Exchange further believes that the proposed rule change is designed to prevent fraudulent and manipulative acts and practices because, as noted by the Commission in the Bitcoin ETP Approval Order, the Exchange's ability to obtain information regarding trading in the Shares and futures from markets and other entities that are members of the ISG (including the CME) would assist the Exchange in detecting and deterring misconduct. In particular, the CME Bitcoin futures market is a large, surveilled, and regulated market that is closely connected with the spot market for Bitcoin and through which the Exchange could obtain information to assist in detecting and deterring potential fraud or manipulation.

The proposed rule change is also designed to prevent fraudulent and manipulative acts and practices because, although the Digital Asset Trading Platform Market is not inherently resistant to fraud and manipulation, the Index serves as a means sufficient to mitigate the impact of instances of fraud and manipulation on a reference price for Bitcoin. Specifically, the Index provides a better benchmark for the price of Bitcoin than the Digital Asset Trading Platform Market price because it (1) tracks the Digital Asset Trading Platform Market price through trading activity at U.S.-Compliant Trading Platforms; (2) mitigates the impact of instances of fraud, manipulation and other anomalous trading activity in real-time through systematic adjustments; (3) is constructed and maintained by an expert third-party index provider, allowing for prudent handling of non-market-related events; and (4) mitigates the impact of instances of fraud, manipulation and other anomalous trading activity concentrated on any one specific trading platform through a cross-trading platform composite index rate. GBTC has used the Index to price the Shares for more than seven years, and the Sponsor believes the Index has proven its ability to (i) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (ii) provide a real-time, volume-weighted fair value of Bitcoin and (iii) appropriately handle and adjust for non-market related events, such that efforts to manipulate the price of Bitcoin would have had a negligible effect on the pricing of the Trust, due to the controls embedded in the structure of the Index. In addition, certain of the Index's Constituent Trading Platforms also have or have begun to implement market surveillance infrastructure to further detect, prevent, and respond to fraud, attempted fraud, and similar wrongdoing, including market manipulation.

The proposed rule change is designed to promote just and equitable principles of trade and to protect investors and the public interest in that there is a considerable amount of Bitcoin price and market information available on public websites and through professional and subscription services. Investors may obtain, on a 24-hour basis, Bitcoin pricing information based on the spot price for Bitcoin from various financial information service providers. The closing price and settlement prices of Bitcoin are readily available from the Digital Asset Trading Platforms and other publicly available websites. In addition, such prices are published in public sources, or on-line information services such as Bloomberg and Reuters. The NAV per Share will be calculated daily and made available to all market participants at the same time. The Trust will provide website disclosure of its NAV and NAV per Share daily. One or more major market data vendors will disseminate for the Trust on a daily basis information with respect to the most recent NAV per Share and Shares outstanding. In addition, if the Exchange becomes aware that the NAV per Share is not disseminated to all market participants at the same time, it will halt trading in the Shares until such time as the NAV per Share is available to all market participants. Quotation and last-sale information regarding the Shares will be disseminated through the facilities of the CTA. The IIV will be widely disseminated on a per Share basis every 15 seconds during the NYSE Arca Core Trading Session (normally 9:30 a.m., E.T., to 4:00 p.m., E.T.) by one or more major market data vendors. The Exchange represents that the Exchange may halt trading during the day in which an interruption to the dissemination of the IIV or the value of the Index occurs. If the interruption to the dissemination of the IIV or the value of the Index persists past the trading day in which it occurred, the Exchange will halt trading no later than the beginning of the trading day following the interruption.

The proposed rule change is designed to perfect the mechanism of a free and open market and, in general, to protect investors and the public interest in that it will facilitate the listing and trading of an additional type of exchange-traded product that will enhance competition among market participants, to the benefit of investors and the marketplace. As noted above, the Exchange has in place surveillance procedures relating to trading in the Shares and may obtain information via ISG from other exchanges that are members of ISG or with which the Exchange has entered into a CSSA. In addition, as noted above, investors will have ready access to information regarding the Trust's NAV per Share, IIV, and quotation and last sale information for the Shares.

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 purposes of the Act. The Exchange notes that the proposed rule change will facilitate the listing and trading of an additional type of exchange-traded product, which will enhance competition among market participants, 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

No written comments were solicited or received with respect to 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 self-regulatory organization consents, the Commission will:

(A) by order approve or disapprove the proposed rule change, or

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

IV. Solicitation of Comments
