bitcoin’s protocol is cryptographically robust and blockchain consensus prevents double-spending. True security depends on protecting private keys: loss or theft hands attackers full control of funds.
bitcoin carries risks: extreme price volatility, evolving regulatory uncertainty, technical vulnerabilities and network issues, plus access risks from custody, keys loss, outages and scams.
Multisig (multi-signature) requires multiple private keys to authorize bitcoin transactions, enhancing security and enabling shared custody, escrow, and corporate wallets without relying on a single signer.
