| ORGANIZATION | 1. ORGANIZATION WisdomTree Bitcoin Fund (the “Fund”) is a Delaware statutory trust organized on March 8, 2021 under Delaware law pursuant to the Delaware Statutory Trust Act (“DTSA”) and a Trust Agreement, as amended from time to time (the “Trust Agreement”). The Fund’s investment objective is to gain exposure to the price of bitcoin, less expenses and liabilities of the Fund’s operations. The Fund issues common shares of beneficial interest (the “Shares”) and expects to operate as an exchange traded fund that will be listed on the Cboe BZX Exchange, Inc. (the “Exchange”) and will trade under the ticker symbol “BTCW.” WisdomTree Digital Commodity Services, LLC (the “Sponsor”) serves as sponsor of the Fund. The Sponsor arranges for the creation of the Fund 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 Fund and prepare marketing materials regarding the Shares, in each case in conjunction with Foreside Fund Services, LLC (the “Marketing Agent”). The sponsor will select the service providers, negotiate the applicable agreements and fees and monitors the performance of the Fund. Delaware Trust Company acts as the trustee of the Fund for the purpose of creating a Delaware statutory trust in accordance with the DTSA. The Trustee is appointed to serve as the trustee of the Fund in the State of Delaware for the sole purpose of satisfying the requirement of Section 3807(a) of the DSTA that the Fund have at least one trustee with a principal place of business in the State of Delaware. The Fund had no operations to date other than matters relating to its organization and registration under the Securities Act of 1933, as amended, and the sale and issuance of 1,000 In the ordinary course of operation, the Fund 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 Fund (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 State Street Bank and Trust Company (“State Street”) the Fund’s administrator (the “Fund Administrator” or the “Cash Custodian”). 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 Fund (known as “Authorized Participants”) will deliver cash to the Fund’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 Fund. Shares initially comprising the same Basket but offered 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 Fund’s assets, and market conditions at the time of a transaction. In the normal course of business, the Fund may enter into contracts that contain a variety of representations or that provide indemnification for certain liabilities. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts and believes such exposure to be remote. |

| Accounting Policies [Abstract] | |

| EXPENSES, ORGANIZATION AND OFFERING COSTS | 3. EXPENSES, ORGANIZATION AND OFFERING COSTS Once operations commence, the Fund will pay the Sponsor a fee (the “Sponsor Fee”) in accordance with the Trust agreement and as set forth in the Prospectus. The Sponsor fee shall be included in the Prospectus prior to the commencement of trading of Shares on the listing exchange. The Sponsor Fee is calculated on a daily basis (accrued at 1/365 of the applicable percentage of the net asset value (the “NAV”) on that day) and paid on a monthly basis. The Sponsor Fee will accrue and be payable in U.S. dollars. The Fund’s only ordinary recurring expense is expected to be the Sponsor Fee. In exchange for the Sponsor’s Fee, the Sponsor has agreed to assume the marketing and the following administrative expenses of the Fund: the fees of the Trustee, the Fund Administrator, Fund Accountant, Transfer Agent, and Marketing Agent, the Custodians’ Fee, Exchange listing fees, SEC registration fees, printing and mailing costs, tax reporting fees, audit fees, license fees and ordinary legal fees and expenses. The Sponsor will pay the costs of the Fund’s organization and the initial sale of the Shares. There is no cap on the amount of these Sponsor paid expenses. The Sponsor may, at its sole discretion and from time to time, waive all or a portion of the Sponsor Fee for stated periods of time. The Fund may incur certain non-recurring expenses that are not assumed by the Sponsor, including but not limited to, taxes and governmental charges, any applicable brokerage commissions, financing charges or fees, Bitcoin network fees and similar transaction fees, expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Fund to protect the Fund or the interests of Shareholders, any indemnification of the Cash Custodian, Coinbase Custody Trust Company LLC (“Bitcoin Custodian”), Fund Administrator or other agents, service providers or counterparties of the Fund and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters related to the Fund. Because the Fund does not have any income, it will need to sell bitcoin to cover the Sponsor’s Fee and expenses not assumed by the Sponsor, if any. The Fund may also be subject to other liabilities (for example, as a result of litigation) that have also not been assumed by the Sponsor. The only source of funds to cover those liabilities will be sales of bitcoin held by the Fund. Even if there are no expenses other than those assumed by the Sponsor, and there are no other liabilities of the Fund, the Fund will still need to sell bitcoin to pay the Sponsors Fee. The result of these sales is a decrease in the amount of bitcoin represented by each Share. To cover the Sponsor’s Fee and expenses not assumed by the Sponsor, the Sponsor or its delegate will cause the Fund (or its delegate) to convert bitcoin into U.S. dollars at the price available through Coinbase, Inc., which is an affiliate of the Bitcoin Custodian. The number of bitcoins represented by a Share will decline each time the Fund pays the Sponsor fee or any Fund expenses not assumed by the Sponsor by selling bitcoins. The Fund is responsible for paying any costs associated with the sale of bitcoin. |
