pro-rata share of the Bitcoin held in such omnibus wallets and/or at Coinbase Connected Venues. In all circumstances the Prime Broker will keep an internal ledger that specifies the assets credited to the
Settlement Balance such that the Trust, its auditors and regulators can identify the Trust’s pro-rata share of the Bitcoin held in omnibus wallets and/or at Coinbase Connected Venues. Neither the Trust
nor the Sponsor have a contractual relationship with the Coinbase Connected Venues utilized by the Custodial Entities.

Insurance

Pursuant to the terms of the Prime Broker Agreement, the Custodian is required to maintain insurance in such types and amounts as
are commercially reasonable for the custodial services it provides. The Custodian has advised the Sponsor that it has insurance coverage pursuant to policies held by Coinbase Global, which procures fidelity (or crime) insurance coverage at
commercially reasonable amounts for the custodial services provided. This insurance coverage is limited to losses of the digital assets the Custodian custodies on behalf of its clients, including the Trust’s Bitcoin, resulting from theft,
including internal theft by employees of Coinbase and its subsidiaries and theft or fraud by a director of Coinbase if the director is acting in the capacity of an employee of Coinbase or its subsidiaries.

Although the Prime Broker is not required to maintain insurance under the terms of the Prime Broker Agreement, the Custodial Entities have
also advised the Sponsor that they maintain insurance coverage pursuant to such policies held by Coinbase Global.

Moreover, while the
Custodian maintains certain capital reserve requirements depending on the assets under custody and to the extent required by applicable law, and such capital reserves may provide additional means to cover client asset losses, the Sponsor does not
know the amount of such capital reserves, and neither the Trust nor the Sponsor have access to such information. The Trust cannot be assured that the Custodian will maintain capital reserves sufficient to cover losses with respect to the
Trust’s digital assets. Furthermore, Coinbase has represented in securities filings that the total value of crypto assets in its possession and control is significantly greater than the total value of insurance coverage that would compensate
Coinbase in the event of theft or other loss of funds.
