Cold storage refers to keeping Bitcoin private keys on devices or mediums not connected to the internet, ensuring enhanced security. Essentially, it's the digital equivalent of a physical vault for Bitcoin. This offline safeguard protects private keys from cyber threats and unauthorized access. Cold storage methods include paper wallets, where private keys are physically written or printed, and hardware wallets, specialized devices designed to store private keys securely.
