WisdomTree Bitcoin Fund (the “Trust”) is a Delaware statutory trust organized on March 8, 2021 under Delaware law pursuant to the Delaware Statutory Trust Act (the “DTSA”) and the Second Amended and Restated Trust Agreement (the “Trust Agreement”). The Trust’s investment objective is to gain exposure to the price of bitcoin, less expenses and liabilities of the Trust’s operations. The Trust is an exchange-traded fund that issues common shares of beneficial interest (the “Shares”) that are listed on the Cboe BZX Exchange, Inc. (the “Exchange”) and trade under the ticker symbol “BTCW”. WisdomTree Digital Commodity Services, LLC (the “Sponsor”) serves as sponsor of the Trust. The Sponsor arranged for the creation of the Trust and is responsible for the ongoing registration of the Shares for public offering in the United States and the listing of Shares on the Exchange. The Sponsor will develop and administer a marketing plan for the Trust and prepare marketing materials regarding the Shares, in each case in conjunction with Foreside Fund Services, LLC (the “Marketing Agent”). The Sponsor selects the service providers, negotiates the applicable agreements and fees and monitors the performance of the Trust. Delaware Trust Company (the “Trustee”) acts as the trustee of the Trust for the purpose of creating a Delaware statutory trust in accordance with the DSTA. The Trustee is appointed to serve as the trustee of the Trust in the State of Delaware for the sole purpose of satisfying the requirement of Section 3807(a) of the DSTA that the Trust have at least one Trustee with a principal place of business in the State of Delaware. Prior to December 31, 2023, the Trust had no operations other than matters relating to its organization and registration under Securities Act of 1933, as amended (the “1933 Act”). WisdomTree, Inc., the parent of the Sponsor, purchased (i) $50,000 in Shares at a price per Share of $50 on December 22, 2023, and (ii) $2,450,000 in Shares at a price per Share of $50 on January 8, 2024, for a total of $2,500,000. On December 16, 2024, WisdomTree, Inc. sold 50,000 shares of the Trust for proceeds $5,637,003 and did not own any shares of the Trust as of that date. On January 10, 2024, the Trust’s registration statement relating to the continuous public offering of its Shares was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) and the Trust commenced trading on the Exchange on January 11, 2024. Coinbase Custody Trust Company LLC (the “Bitcoin Custodian”) is the custodian of the Trust with respect to the Trust’s bitcoin holdings, and The Bank of New York Mellon ("BNY") serves as cash custodian, administrator, fund accountant, and transfer agent for the Trust (the "Trust Administrator" or the "Cash Custodian"). In the ordinary course of operation, the Trust will sell or redeem its Shares, in blocks of 5,000 Shares (a “Basket”) based on the quantity of bitcoin attributable to each Share of the Trust (net of accrued but unpaid expenses and liabilities). For a subscription of Shares, the subscription shall be in the amount of cash needed to purchase the amount of bitcoin represented by the Basket being created, in each case as calculated by the Trust Administrator. For a redemption of Shares, the Sponsor shall arrange for the bitcoin represented by the Basket to be sold and the cash proceeds distributed. Financial firms that are authorized to purchase or redeem Shares with the Trust (known as “Authorized Participants”) will deliver cash to the Trust’s account with the Cash Custodian in exchange for Shares when they purchase Shares and will receive cash (from the Cash Custodian), when they redeem Shares with the Trust. Shares initially comprising the same Basket but sold by the Authorized Participants to the public at different times may have different offering prices, which depend on various factors, including the supply and demand for Shares, the value of the Trust’s assets, and market conditions at the time of a transaction.
