What Is It?
Cold storage refers to keeping private keys completely offline and disconnected from the internet.
Origin
Cold storage became best practice after early exchange hacks in the 2010s revealed the danger of keeping large balances in internet-connected wallets.
Why It Matters
Cold storage protects against remote attacks and is the standard for long-term institutional digital asset holdings.

Market Mechanics
Assets are held through hardware wallets, air-gapped computers, paper backups, or institutional vault systems. Transactions are signed offline and broadcast separately.
