The Binance and KuCoin exchanges are for me the main exchanges on which I trade. They are equally good at work. And the fact that one of them was hacked, absolutely nothing to say about the great reliability of the second, maybe it's just someone's flaw)
I also use these exchanges. But I don’t like that liquidity is very likely for many trading pairs on Kucoin. We need to increase the trading volumes on Kucoin.
