#CryptoSecurity101 First, choose reputable exchanges with strong regulatory compliance and cold-storage policies. Enable multi-factor authentication on every account—SMS isn’t enough; prefer hardware or authenticator apps. Use a dedicated email and a unique, randomly generated password stored in an encrypted manager. Withdraw long-term holdings to hardware wallets, verifying addresses via device screens. Keep seed phrases offline, split or etched on metal, never photographed. Regularly update firmware and double-check URLs to avoid phishing. Monitor transaction histories and revoke obsolete smart-contract approvals. Finally, stay informed—threat landscapes evolve as fast as blockchains. Invest time now; prevent losses later.
