Binance's SAFU was the only time they ever used to reimburse the hacked funds which happened in 2019 for about 40 million at that time.
I believe binance were able to cover the losses in full and continue operation because of the amount that was lost, it was not an amount that would lead to their collapse. However, take note that funds are not safu if you store them in binance, if they get hit with a serious security breach and lose a lot of money, it would be trouble for anyone who stores their funds in binance.
I know little about other exchanges, but Bitget i actually followed their Protection Fund Valuation Report announcement for months and i have never seen a foul play for once in my own view. I even saw the recent one on January 22nd that they had an all-time-high of $690 million. Same with some unpopular exchanges.
Are you one of their many shillers.
