How do exchanges & wallet providers control bitcoin?
As a cryptocurrency enthusiast, I'm curious about the mechanisms behind the control of Bitcoin by exchanges and wallet providers. Could you elaborate on how these entities ensure the security and management of Bitcoin transactions? Do they have direct access to private keys, or do they employ secure protocols to safeguard user funds? Additionally, what measures do they take to prevent fraud and unauthorized access to Bitcoin wallets? I'm particularly interested in understanding the technical and operational aspects of this process.
