A cold wallet is a cryptocurrency storage device or method that is kept offline, disconnected from the internet. This physical separation from online networks significantly reduces the risk of remote hacking and unauthorized access to private keys. Cold wallets are considered the most secure option for storing substantial amounts of digital assets for extended periods.
Context
