What Is a Cold Wallet?

A cold wallet (also called cold storage) is any cryptocurrency wallet that is not connected to the internet. This makes it virtually immune to online hacking, phishing, and malware attacks.

Types of Cold Wallets

• Hardware Wallets: Physical devices like Ledger that store keys on a secure chip. Most popular and user-friendly.
• Paper Wallets: Private keys printed on paper. Simple but fragile.
• Steel/Metal Backups: Recovery phrases engraved on metal plates for durability.

Why Use a Cold Wallet?

Since your private keys never touch the internet, they cannot be stolen by hackers, malware, or phishing attacks. Cold wallets are recommended for any crypto you are not actively trading.

Cold Wallet vs Hot Wallet

Hot wallets (MetaMask, Trust Wallet) are convenient for daily use but expose keys to online threats. The ideal approach: use a hot wallet for small transactions and a cold wallet for long-term storage.
