1. Store your wallet off the internet by backing it up on an external storage device such as a USB drive, CD-ROM, or hard drive.
2. Utilize two-factor authentication (2FA) to safeguard your wallet from outside attackers.
3. Make sure you encrypt the wallet with a strong password that can’t be easily guessed.
4. Ensure that the cold storage wallet is stored in a safe and secure location, such as a safety deposit box or an area with restricted access.
5. Use a hardware wallet, such as a Trezor or Ledger, for added security.
6. Always keep backup keys and passwords in a separate, secure location.
