Maintaining cryptocurrency securely requires strict, proactive management of private keys and digital access. The primary goal is to keep keys offline ("cold") to prevent unauthorized access, ensuring you are the sole owner of your assets.

Key Points for Secure Crypto Maintenance:

Use Cold/Hardware Wallets: Store the vast majority of assets (90%) in cold storage devices (Ledger, Trezor, Tangem) that remain offline.

Secure Seed Phrases Offline: Write your 12-24 word recovery phrase on paper or metal and store it in a physical, secure, and fireproof location. Never take a photo, screenshot, or store it in the cloud.

Enable Multi-Factor Authentication (2FA): Use authenticator apps (e.g., Google Authenticator) for exchange accounts. Avoid SMS-based 2FA, which is vulnerable to SIM-swapping.

Use Separate Wallets: Utilize hot wallets (mobile/browser) only for small, active trading amounts (10%), keeping the rest in cold storage.

Whitelisting Addresses: Enable address whitelisting on exchanges to restrict withdrawals to approved, trusted addresses only.
