Crypto Security Best Practices: How to Protect Your Holdings
The core of crypto security is storing long-term holdings on a hardware wallet, keeping your seed phrase offline, protecting accounts with unique passwords and security-key 2FA, and doing transactions from a clean device. A regulated exchange is fine for smaller amounts, and the rule of thumb users repeat is simple: as soon as losing the sum would hurt, move it to a hardware wallet. Seed phrase handling matters as much as the wallet itself. Never store it digitally, meaning no photos and no cloud backups. Write it on paper or engrave it on metal, keep it separate from your devices, and store copies in multiple secure locations. Generate the phrase fresh on the hardware wallet itself rather than trusting anything pre-generated, and buy the device directly from the manufacturer instead of a third-party reseller like Amazon so you know it is authentic. Daily habits complete the setup. Use a password manager and hardware security keys for 2FA instead of SMS, since SMS is open to SIM swapping. Consider a separate computer for crypto activity or booting TailsOS from a USB drive, never click links in emails or messages, and simulate transactions before signing them. Stay quiet about how much you hold, review the whole setup every few months, and for Ethereum consider a Safe multisig that requires multiple signers to approve each transaction.
