Except as specifically noted, the discussion below assumes that each U.S. Holder will
acquire all of its Shares on the same date for the same price per Share and solely for cash (or, if In-Kind Regulatory Approval is obtained in the future, solely for Bitcoin that were originally acquired by
the U.S. Holder for cash on the same date).

As discussed in the section entitled “Creation and Redemption of Shares,” if In-Kind Regulatory Approval is obtained in the future, a U.S. Holder may be able to acquire Shares of the Trust by contributing Bitcoin in kind to the Trust (either directly or through an Authorized Participant
acting as agent of the U.S. Holder). Assuming that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes, such a contribution should not be a taxable event to the U.S. Holder.

For U.S. federal income tax purposes, each U.S. Holder will be treated as owning an undivided interest in the Bitcoin held in the Trust and
will be treated as directly realizing its pro rata share of the Trust’s income, gains, losses and deductions. When a U.S. Holder purchases Shares solely for cash, (i) the U.S. Holder’s initial tax basis in its pro rata share of the
Bitcoin held in the Trust will be equal to the amount paid for the Shares and (ii) the U.S. Holder’s holding period for its pro rata share of such Bitcoin will begin on the date of such purchase. If, in the future, In-Kind Regulatory Approval is obtained and a U.S. Holder acquires Shares in exchange for Bitcoin, (i) the U.S. Holder’s initial tax basis in its pro rata share of the Bitcoin held in the Trust would be
equal to the U.S. Holder’s tax basis in the Bitcoin that the U.S. Holder transferred to the Trust and (ii) the U.S. Holder’s holding period for its pro rata share of such Bitcoin generally would include the period during which the
U.S. Holder held the Bitcoin that the U.S. Holder transferred to the Trust. The
