#保持SAFU "Keep SAFU" is a widely used slogan in the cryptocurrency community, first posted by Binance founder Changpeng Zhao (CZ) on Twitter to reassure users during market turmoil or when facing hacking attacks. SAFU stands for "Secure Asset Fund for Users," which is an emergency fund established by Binance to protect user assets. This concept not only symbolizes Binance's commitment to user trust but has also become an important symbol in both decentralized finance (DeFi) and centralized finance (CeFi) that emphasizes the protection of asset security. In the face of market uncertainty, SAFU represents a guarantee of asset security, allowing investors to feel more at ease in the face of risks.
