#CryptoSecurity101 is essential for every investor. Always use two-factor authentication (2FA) on all your accounts. Prefer hardware wallets (cold storage) for large amounts, keeping your private keys offline. Have strong and unique passwords, and never reuse them. Stay alert against phishing and scams: always verify URLs and do not share your seed phrase. Research thoroughly before interacting with new projects. Your security is your responsibility in the crypto space!
