Binance CEO CZ tweeted that to adjust to recent price fluctuations, Binance has topped up the Secure Asset Fund for Users (SAFU) insurance fund to $1 billion USD equivalent again, with $BUSD and $BNB addresses about $700 million and $BTC addresses about $300 million.
The Secure Asset Fund for Users is an emergency insurance fund that was established by Binance in July 2018 to protect users' funds. When the fund was established, Binance committed a percentage of trading fees in order to grow it to a sizable level to safeguard users.
