Accounting Policies [Abstract] |
Significant Accounting Policies | The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. Basis of Presentation The financial statements have been prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”). The Trust is an investment company and follows the specialized accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies. Use of Estimates The preparation of the financial statements in accordance 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 these financial statements. Actual results could differ from those estimates. Cash Generally, the Trust does not intend to hold any cash. Cash includes non-interest-bearing unrestricted cash with one (1) institution. Cash in a bank deposit account, at times, may exceed U.S. federally insured limits. The Trust has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on such bank deposits. Investment Transactions and Revenue Recognition The Trust records its investment transactions on a trade date basis and changes in fair value are reflected as net change in unrealized appreciation or depreciation on investment in bitcoin. Realized gains and losses are calculated using the specific identification method. Realized gains and losses are recognized in connection with transactions including settling obligations for the Sponsor Fee in bitcoin. Investment Valuation - Principal Market Net Asset Value (“NAV”) To determine which market is the Trust's principal market (or in the absence of a principal market, the most advantageous market) for purposes of calculating the Trust's net asset value in accordance with U.S. GAAP (“Principal Fair Market NAV”), the Trust follows ASC Topic 820-10, Fair Value Measurement, which outlines the application of fair value accounting. ASC 820-10 determines fair value to be the price that would be received for bitcoin in a current sale, which assumes an orderly transaction between market participants on the measurement date. ASC 820-10 requires the Trust to assume that bitcoin is sold in its principal market to market participants or, in the absence of a principal market, the most advantageous market. Market participants are defined as buyers and sellers in the principal or most advantageous market that are independent, knowledgeable, and willing and able to transact. The Trust only receives bitcoin in connection with a creation order from the Authorized Participant (or a Liquidity Provider) and does not itself transact on any Digital Asset Markets. Therefore, the Trust looks to market-based volume and level of activity for Digital Asset Markets. The Authorized Participant(s), or a Liquidity Provider, may transact in a Brokered Market, a Dealer Market, Principal-to-Principal Markets and Exchange Markets (“Trading Platform Markets”), each as defined in the FASB ASC Master Glossary (collectively, “Digital Asset Markets”). In determining which of the eligible Digital Asset Markets is the Trust's principal market, the Trust reviews these criteria in the following order: First, the Trust reviews a list of Digital Asset Markets that are US accessible, have historically provided publicly available data, and are exchanges that Bitwise normally transact on. Specifically, the Trust utilizes a third-party valuation vendor, Lukka, Inc., to identify publicly available, well established and reputable crypto asset exchanges selected in their sole discretion. Second, Lukka, Inc. sorts these Digital Asset Markets from high to low by market-based volume and level of activity of bitcoin traded on each Digital Asset Market. For the year ended December 31, 2025, this sort was performed for Digital Asset Markets for the period mid-November through mid-December 2025. Third, Lukka, Inc. then reviews pricing fluctuations and the degree of variances in price on each Digital Asset Market during the 60 minutes prior to 4:00 pm. EST for bitcoin to identify any material notable variances that may impact the volume or price information of a particular Digital Asset Market. Fourth, Lukka, Inc. then selects a Digital Asset Market as its principal market based on the highest market-based volume level of activity and price stability in comparison to the other Digital Asset Markets on the list. As of December 31, 2025, Lukka, Inc. included Binance, Bitfinex, Bitflyer, Bitstamp, Bullish, Coinbase, Crypto.com, Gate.io, Gemini, HitBTC, Huobi, itBit, Kraken, KuCoin, LMAX, MEXC Global, OKX and Poloniex as its primary Exchange Markets in consideration. At December 31, 2025, the principal market and the principal market price for bitcoin, which is composed of the majority of the Trust’s assets as of December 31, 2025, was Crypto.com with a price of $87,544.00. The Trust determines its principal market (or in the absence of a principal market the most advantageous market) annually and conducts a quarterly analysis to determine (i) if there have been recent changes to each Digital Asset Market’s trading volume and level of activity in the trailing twelve months, (ii) if any Digital Asset Markets have developed that the Trust has access to, or (iii) if recent changes to each Digital Asset Market's price stability have occurred that would materially impact the selection of the principal market and necessitate a change in the Trust's determination of its principal market. The cost basis of the bitcoin received by the Trust in connection with a creation order is recorded by the Trust at the fair value of bitcoin at 4:00 p.m., EST, on the creation date for financial reporting purposes. The cost basis recorded by the Trust may differ from proceeds collected by the Authorized Participant from the sale of the corresponding Shares to investors. Various inputs are used to determine the fair value of assets and liabilities. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means; and Level 3: Unobservable inputs, including the Trust's assumptions used in determining the fair value of investments, where there is little or no market activity for the asset or liability at the measurement date. The cost basis of the investment in bitcoin recorded by the Trust for financial reporting purposes is the fair value of bitcoin at the time of transfer. The cost basis recorded by the Trust may differ from proceeds collected by the Authorized Participant from the sale of the corresponding Shares to investors. The following summarizes the Trust’s assets accounted for at fair value at December 31, 2025 (amounts in thousands):
|  | Level 1 |  |  | Level 2 |  |  | Level 3 |  |  | Total |
Assets |  |  |  |  |  |  |  |  |  |  |  |
Investment in bitcoin, at fair value |  | $ | 3,367,647 |  |  | $ | — |  |  | $ | — |  |  | $ | 3,367,647 |

Calculation of Net Asset Value (NAV) and NAV Per-Share On each business day, as soon as practicable after 4:00 p.m. EST, the NAV of the Trust is obtained by subtracting all accrued fees and other liabilities of the Trust from the fair value of the bitcoin and other assets held by the Trust. The Bank of New York Mellon (the “Administrator”) computes the NAV per Share by dividing the NAV of the Trust by the number of Shares outstanding on the date the computation is made. Income Taxes The Trust is classified as a “grantor trust” for U.S. federal income tax purposes. As a result, the Trust itself is not subject to U.S. federal income tax. Instead, the Trust’s income and expenses “flow through” to the shareholders, and the Administrator reports the Trust’s income, gains, losses, and deductions to the Internal Revenue Service on that basis. The Sponsor has analyzed applicable tax laws and regulations and their application to the Trust, and does not believe that there are any uncertain tax positions that require recognition of a tax liability as of December 31, 2025. The Trust is required to determine whether its tax positions are more likely than not to be sustained on examination by the applicable taxing authority, based on the technical merits of the position. Tax positions not deemed to meet a more likely than not threshold would be recorded as a tax expense in the current year. As of December 31, 2025, the Trust has determined that no provision for income taxes is required and no liability for unrecognized tax benefits has been recorded. The Trust does not expect that its assessment related to unrecognized tax benefits will materially change over the next 12 months. However, the Trust’s conclusions may be subject to review and adjustment at a later date based on factors including, but not limited to, the nexus of income among various tax jurisdictions; compliance with U.S. federal, U.S. state, and tax laws of jurisdictions in which the Trust operates in; and changes in the administrative practices and precedents of the relevant authorities. The Trust is required to analyze all open tax years. Open tax years are those years that are open for examination by the relevant income taxing authority. As of December 31, 2025, all tax years since inception remain open for examination. There were no examinations in progress at period end. Organizational and Offering Costs The costs of the Trust’s organization and the initial offering of the Shares are borne directly by the Sponsor. The Trust is not obligated to reimburse the Sponsor.
