Accounting Policies [Abstract]
Use of Estimates	(a) Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Investment Transactions	(b) Investment Transactions The Trust purchases bitcoin upon the net creation of Shares and sells bitcoin upon the net redemption of Shares. Transactions are recorded on a trade-date basis. Realized gains (losses) and changes in unrealized gains (losses) on open positions are determined on a specific identification basis and are recognized in the statement of operations in the period in which the sale occurred or the changes in unrealized occurred. The Trust utilizes an exchange traded price from the principal market for bitcoin as of 4:00 p.m. ET on the Trust’s financial statement measurement date to value the bitcoin held by the Trust. The Sponsor determines in its sole discretion the valuation sources and policies used to prepare the Trust’s financial statements in accordance with U.S. GAAP.
Indemnifications	(c) Indemnifications The Sponsor and its affiliates (each a “Covered Person”) will be indemnified by the Trust and held harmless against any loss, judgment, liability, expense incurred or amount paid in settlement of any claim sustained by it in connection with the Covered Person’s activities for the Trust, without fraud, gross negligence, bad faith, willful misconduct or a material breach of the Trust Agreement on the part of such indemnified party arising out of or in connection with the performance of its obligations under the Trust Agreement and under each other agreement entered into by the Sponsor in furtherance of the administration of the Trust (including, without limiting the scope of the foregoing, any Participant Agreement) or any actions taken in accordance with the provisions of the Trust Agreement. The Trustee and any of the officers, directors, employees and agents of the Trustee shall be indemnified by the Trust as primary obligor and held harmless against any loss, damage, liability, claim, action, suit, cost, expense, disbursement (including the reasonable fees and expenses of counsel), tax or penalty of any kind and nature whatsoever, arising out of, imposed upon or asserted at any time against such indemnified person in connection with the performance of its obligations under the Trust Agreement, the creation, operation or termination of the Trust or the transactions contemplated therein; provided, however, that neither the Trust nor the Sponsor shall be required to indemnify any such indemnified person for any such expenses which are a result of the willful misconduct, bad faith or gross negligence of such indemnified person. The Trust’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Trust, which cannot be predicted with any certainty.
Federal Income Taxes	(d) Federal Income Taxes The Sponsor intends to take the position that the Trust will be treated as a grantor trust under the Internal Revenue Code of 1986, as amended. If so qualified, the Trust will not be subject to U.S. federal income tax to the extent it distributes substantially all of its investment income and capital gains to shareholders. Therefore, no federal income tax provision is required. Rather, a pro rata portion of the Trust’s income, gain, losses and deductions will “flow through” to each beneficial owner of Shares.
