| Accounting Policies [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Accounting, Policy [Policy Text Block] |
The following significant accounting policies are consistently followed by the Trust in the preparation of its financial statements in conformity with U.S. GAAP. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

| Investment, Policy [Policy Text Block] |
Coinbase Custody Trust Company, LLC (the “Bitcoin Custodian”) is responsible for safekeeping the bitcoin owned by the Trust. Anchorage Digital Bank N.A. is the “Additional Bitcoin Custodian” for the Trust. At the current time, the Sponsor has no plans to move any of the Trust’s bitcoin to the Additional Bitcoin Custodian. The Bitcoin Custodian and the Additional Bitcoin Custodian are appointed by the Trustee.
The net asset value of the Trust on any given day is computed by subtracting the Trust’s accrued expenses and liabilities, which include the Trust’s options positions from the value of the Trust’s total assets, which consist of: (1) the Trust’s bitcoin, IBIT shares, and cash; (2) any earnings on those assets; and (3) any other assets of the Trust, in each case as of the close of trading on that day, each determined by the Trustee pursuant to policies established from time to time by the Trustee or its affiliates or otherwise described herein. The Trust’s periodic financial statements are prepared in accordance with the Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurement” and utilize an exchange-traded price from the Trust’s principal market for bitcoin as of 11:59 p.m. Eastern Time (“ET”) on the Trust’s financial statement measurement date. 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. The Trust engages a third-party vendor to obtain a price from a principal market for bitcoin, which is determined and designated by such third-party vendor daily based on its consideration of several exchange characteristics, including oversight, and the volume and frequency of trades.
The Sponsor has the exclusive authority to determine the Trust’s net asset value, which it has delegated to the Trustee under the Trust Agreement. The Trustee has delegated to the Trust Administrator the responsibility to calculate the net asset value of the Trust and the net asset value per Share (“NAV”), based on a pricing source selected by the Trustee. In determining the Trust’s net asset value, the Trust Administrator values the bitcoin held by the Trust based on an index (the “Index”), unless the Sponsor in its sole discretion determines that the Index is unreliable. The methodology used
to calculate the Index price to value bitcoin in determining the net asset value of the Trust may not be deemed consistent with U.S. GAAP. The CME CF Bitcoin Reference Rate – New York Variant for the Bitcoin – U.S. Dollar trading pair (the “CF Benchmarks Index”) shall constitute the Index, unless the CF Benchmarks Index is not available or the Sponsor in its sole discretion determines the CF Benchmarks Index is unreliable as the Index and therefore determines not to use the CF Benchmarks Index as the Index. If the CF Benchmarks Index is not available or the Sponsor determines, in its sole discretion, that the CF Benchmarks Index is unreliable (together a “Fair Value Event”), the Trust’s holdings may be fair valued on a temporary basis in accordance with the fair value policies approved by the Trustee.
Additionally, the Trust Administrator monitors for unusual prices and escalates to the Trustee if detected. If the CF Benchmarks Index is not used, the Trust will notify Shareholders in a prospectus supplement, in its periodic Exchange Act reports and/or on the Trust’s website. The Trust Administrator calculates the net asset value of the Trust and the NAV once on each day other than a Saturday or a Sunday or a day on which NASDAQ is closed for regular trading (a “Business Day”). The NAV for a normal trading day will be released after 4:00 p.m. ET. Trading during the core trading session on NASDAQ typically closes at 4:00 p.m. ET. However, NAVs are not officially released until after the completion of a comprehensive review of the NAV and prices utilized to determine the NAV of the Trust by the Trust Administrator. Upon the completion of the end of day reviews by the Trust Administrator the NAV is released to the public typically by 5:30 p.m. ET and generally no later than 8:00 p.m. ET. The period between 4:00 p.m. ET and the NAV release after 5:30 p.m. ET (or later) provides an opportunity for the Trust Administrator and the Trustee to detect, flag, investigate, and correct unusual pricing should it occur and implement a Fair Value Event, if necessary. Any such correction could adversely affect the value of the Shares.
The Trust’s periodic financial statements may not utilize the net asset value of the Trust to the extent the methodology used to calculate the Index is deemed not to be consistent with U.S. GAAP.
Gain or loss on sales of bitcoin is calculated on a trade date basis using the average cost method.
The following table summarizes activity in bitcoin for the period from April 21, 2026 (Date of Seeding) to June 30, 2026:

| Derivatives, Policy [Policy Text Block] |
The Trust will purchase IBIT shares in the market using cash received from Authorized Participants and will write (sells) covered call options primarily on IBIT shares to generate premium income. All options written by the Trust will be U.S. exchange-listed. Options written on IBIT may be standardized options or Flexible Exchange (“FLEX”) options to provide flexibility in the exercise prices and expirations and to manage exposure. The Trust will write standardized IBIT options and, based on a number of factors, FLEX IBIT options. Such factors may include, among other things, market conditions, options liquidity, and options’ strike price. The Trust may also write standardized index options. The Trust’s options will generally have monthly expirations but may vary in term, to achieve the Trust’s investment objective.
An option is a contract that gives the purchaser (the “option holder”), in exchange for a premium the right but not the obligation to buy (a “call option”) or sell (a “put option”) an underlying asset, or settle for cash in an amount based on an underlying asset, rate, or index at a specified price (the “exercise price”) during a period of time or on a specified date. When the Trust writes (sells) a call option, it receives a premium and gives the purchaser of the option the right to purchase from the Trust the IBIT shares at an exercise price by or on the expiration date. The options the Trust writes may be European style, meaning they are exercisable at the exercise price only on the expiration date, or American style, meaning they can be exercised at any time on or prior to their expiration date. The Trust typically trades options that expire monthly but may vary in term, to achieve the Trust’s investment objective.
In addition to purchasing IBIT shares to post as collateral for options, the Trust will also hold IBIT shares to meet its liquidity needs. As a result, the Trust fully participates in market gains or declines of bitcoin through its IBIT shares not held as collateral. Additionally, the Trust fully participates in market gains or declines of bitcoin through its bitcoin holdings.
If the Trust buys a call option, it pays a premium and receives the right, but not the obligation, to purchase IBIT shares or another reference asset at an exercise price by or on the expiration date. However, the Trust expects to purchase options only to close out existing positions on options contracts where it is the seller in order to roll, or extend, the expiration date of its position in the options contracts where it acts as seller. When the Trust rolls an option, the purchased option contract closes out the old option contract that was sold and the Trust has no further obligations under such old option contract. The Trust’s only option exposure is under the new option that it sold in respect of the new, extended expiration date.
Please refer to Note 9 for additional disclosures regarding the Trust’s investments in options written.

| Securities Transactions Income and Expense Recognition [Policy Text Block] |
Securities transactions are accounted for on the trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Dividend income and capital gain distributions from the underlying trusts, if any, are recorded on the ex-dividend date.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Calculation of Net Asset Value [Policy Text Block] |
On each Business Day, as soon as practicable after 4:00 p.m. ET, the net asset value of the Trust is obtained by subtracting all accrued fees, expenses and other liabilities of the Trust from the total assets held by the Trust. The Trust Administrator computes the NAV by dividing the net asset value of the Trust by the number of Shares outstanding on the date the computation is made.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents, Policy [Policy Text Block] |
Cash includes non-interest bearing, non-restricted cash maintained with one banking institution. Cash in a bank deposit account, at times, may exceed U.S. federally insured limits.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Offering of the Shares [Policy Text Block] |
Shares are issued and redeemed continuously in aggregations of 20,000 Shares (a “Basket”) or integral multiples thereof, based on the quantity of bitcoin attributable to each Share (net of accrued but unpaid Sponsor’s fee and any accrued but unpaid expenses or liabilities). Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only registered broker-dealers that are eligible to settle securities transactions through the book entry facilities of the Depository Trust Company and that have entered into a contractual arrangement with the Sponsor governing, among other matters, the creation and redemption of Shares (such broker-dealers, the “Authorized Participants”), can place orders to receive Baskets in exchange for cash, bitcoin and/or IBIT shares. Baskets may be redeemed by the Trust in exchange for an amount of bitcoin and/or IBIT shares corresponding to their redemption value or for the cash proceeds from selling the amount of bitcoin and/or IBIT shares corresponding to their redemption value.
In connection with cash creations and redemptions, the Trust engages in bitcoin transactions for converting cash into bitcoin (in association with purchase orders) and bitcoin into cash (in association with redemption orders) by choosing, in its sole discretion, to trade directly with third parties (each, a “Bitcoin Trading Counterparty”), who are not registered broker-dealers pursuant to written agreements between such Bitcoin Trading Counterparties and the Trust, or choosing to trade through Coinbase, Inc. (the “Prime Execution Agent”) acting in an agency capacity with third parties through its Coinbase Prime service pursuant to the Prime Execution Agent Agreement.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Distributions [Policy Text Block] |
Premiums and other income received by the Trust on its assets may be used to acquire additional assets or, in the discretion of the Sponsor, distributed to shareholders. The Trust is under no obligation to make periodic distributions to shareholders. Distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Trust.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Tax, Policy [Policy Text Block] |
The Trust is treated as a partnership for federal, state and local income tax purposes.
No provision for federal, state, and local income taxes has been made in the accompanying financial statements because the Trust is not subject to income taxes. Shareholders are individually responsible for their own tax payments on their proportionate share of income, gain, loss, deduction, expense and credit.
The Sponsor has analyzed the tax positions as of June 30, 2026, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segment Reporting, Policy [Policy Text Block] |
The Chief Financial Officer of the Sponsor acts as the Trust’s Chief Operating Decision Maker (“CODM”) and is responsible for assessing performance and allocating resources with respect to the Trust. The CODM has concluded that the Trust operates as a single operating segment since the Trust has a single investment strategy as disclosed in its prospectus, against which the CODM assesses performance. The financial information provided to and reviewed by the CODM is presented within the Trust’s financial statements. |
