Yeah youre right! no CEX is flawless Binance, OKX, Bitget, Bybit, Kucoin and many more theyve all had downtime before. Thats why I always keep accounts on a only limited cex, it’s just smart risk management and same way you diversify assets. Relying on one exchange is not good. But its always better to keep the funds or asset on a non custodial wallet for maximum protection.
