Arkham: Strategy transfers 3568 BTC through internal transfer of Fidelity custody

Arkham analyst Emmett Gallic stated that Strategy's transfer of 3568 BTC was not a sale or external transfer, but rather an internal fund transfer within the Fidelity custody system. Fidelity considers the BTC deposited by customers as interchangeable assets and transfers them, with the relevant addresses marked as Fidelity addresses.
