In the crypto world, 'SAFU' is not only the security fund concept proposed by Binance, but also a reminder for investors to stay vigilant. In the face of market corrections or hacking risks, keeping funds safe is always the top priority. It is recommended that everyone enable two-factor authentication, store assets in cold wallets, and avoid blindly chasing highs or clicking on suspicious links. Technology may bring opportunities, but security awareness is the foundation for survival.
