#StaySAFU is a phrase commonly associated with Binance, one of the largest cryptocurrency exchanges. SAFU stands for Secure Asset Fund for Users, which is a fund Binance created to protect users' assets in case of a security breach or hack.

The phrase became popular as a slogan to remind users that Binance is committed to safeguarding their funds, and it serves as reassurance that the platform has security measures in place.

The SAFU fund is intended to cover losses from unforeseen events and hacking incidents, helping to maintain user confidence in the platform.
