What it is
In self-custody, the owner of cryptocurrency holds the private keys necessary to access and spend their funds, granting them complete control and eliminating reliance on intermediaries. This contrasts with keeping assets on an exchange, where the exchange technically holds the private keys. Self-custody empowers users with full ownership, adhering to the "not your keys, not your coins" principle, but also places full responsibility for security on the individual.
Self-custody is a fundamental tenet of the Bitcoin ethos, emphasizing financial sovereignty. It frequently makes news during periods of exchange insolvency or security breaches, highlighting the risks of third-party custodians. Hardware wallets and multi-signature setups are common tools for self-custody, offering enhanced security measures. Understanding self-custody is crucial for investors wanting to fully control their digital assets and mitigate counterparty risk.
Why it matters
Self-custody is vital for retail investors seeking full control and security over their Bitcoin, protecting against exchange failures or hacks.
