The revisions include, but are not limited to: (1) providing that the Trust's ordinary recurring expense will be the management fee that is accrued daily by applying a 0.49% annualized rate to the Trust's net asset value and paid monthly in arrears to the Sponsor and, as partial consideration for its receipt of the management fee, the Sponsor will bear the routine operational, administrative and other ordinary fees and expenses of the Trust, including the fees of the Trustee, Trust Administrator, Fund Accountant, Transfer Agent, and Custodians, Listing Exchange fees, SEC registration fees, printing and mailing costs, tax reporting fees, audit fees, license fees and ordinary legal fees and expenses; and (2) establishing the issuance and redemption of Shares only in blocks of 10,000 or integral multiples thereof (each, a "Basket"), based on the quantity of Bitcoin attributable to each Share (net of accrued but unpaid renumeration due to the Sponsor and any accrued but unpaid expenses or liabilities) to authorized participants in exchange for the delivery of Bitcoin or cash.
