in my opinion the better one is Binance, because Binance exchange is easier for me to get profit, so I prefer to trading at Binance rather than at KuCoin, besides that I think coin in Binance are very much and of course the volume of coin also very high, so it's very easy for me to sell and buy coin without having to be afraid if one day I can't sell the coin, because the volume on Binance exchange is very high and of course Binance is the biggest exchange for now, therefore I prefer to trading at Binance and in my opinion Binance is indeed better than KuCoin for now.
