What Is Bitcoin Self-Custody?

Self-custody refers to an individual's direct ownership and control over their bitcoins. It signifies that only the owner has access to their cryptocurrency, ensuring total autonomy over transactions, similar to holding funds in a personal bank account. This control is enabled by cryptographic keys stored in digital wallets, which the owner must keep secure. Unlike traditional banks, no third party or government can freeze or control these funds. It embodies the phrase "not your keys, not your coins," emphasizing the importance of personal ownership and security in the decentralized financial landscape.
