#StaySAFU "Stay SAFU" is a popular phrase in the cryptocurrency community, derived from the acronym "SAFU," which stands for "Secure Asset Fund for Users." This fund was established by Binance in 2018 to protect users' assets in extreme situations, such as hacks or system failures. The term gained popularity after Binance's CEO, Changpeng Zhao, tweeted "Funds are safe" during an unscheduled maintenance, which was humorously transformed into "Funds are SAFU" by a viral video. Over time, "SAFU" evolved into a meme and a slang term synonymous with "safe." Thus, "Stay SAFU" serves as both a reminder and a reassurance to prioritize security in the volatile crypto world.
