#保持SAFU "Stay SAFU" is a popular phrase in the cryptocurrency community, originating from a tweet by Binance founder Changpeng Zhao (CZ) during an unexpected maintenance in 2018. Although it was initially just a slip of the tongue, "SAFU" quickly evolved into an abbreviation representing **"Secure Asset Fund for Users"** and became a slogan in the community for **"Stay Safe"** and **"Protect Your Assets"**.
Therefore, the core meaning of "Stay SAFU" is:
