How Does the Custody Requirement for a Spot Bitcoin ETF Differ from a Futures ETF?
A spot Bitcoin ETF requires the physical custody of the underlying Bitcoin, necessitating the use of highly secure, regulated, and often cold-storage-focused digital asset custodians. A futures Bitcoin ETF does not hold physical Bitcoin; its assets are typically cash and short-term Treasury bills held as collateral for the futures contracts, which are centrally cleared.
This significantly reduces the digital asset custody risk.
