The Osprey Bitcoin Trust (OBTC) is a U.S.-based investment fund that offers investors a straightforward way to gain exposure to Bitcoin through traditional brokerage accounts. Launched in February 2021, OBTC was introduced with a competitive management fee of 0.49%, positioning it as one of the most cost-effective publicly traded Bitcoin funds at the time. The trust is managed by Osprey Funds, a firm dedicated to providing secure and transparent digital asset investment products. OBTC's assets are securely held by Coinbase, serving as the fund's custodian. (ospreyfunds.io)

In August 2024, Bitwise Asset Management announced plans to acquire OBTC's assets, aiming to integrate them into its own Bitcoin ETF. However, this acquisition was not completed. Subsequently, in January 2025, Osprey Funds declared its intention to convert OBTC into an exchange-traded fund (ETF), filing a Registration Statement on Form S-1 with the Securities and Exchange Commission to facilitate this transition.
