#StaySAFU The phrase "Stay Safu" in the crypto world is an exhortation for security and caution. "SAFU" is an acronym that originated from a typo by Binance CEO, Changpeng Zhao ("CZ"), who tweeted "Funds are safe" during unexpected maintenance in 2018. The mistake became a meme and, subsequently, "SAFU" was adopted by the crypto community to indicate safety.

In addition to its anecdotal origin, "SAFU" is also the acronym for "Secure Asset Fund for Users," an emergency fund created by Binance to protect users in case of hacking or unforeseen events. Thus, "Stay Safu" encapsulates a dual meaning: it invites personal protection.
