Personally, I prefer KuCoin, since their UI looks really nice and I like the KCS bonus (I referred myself ) Also they add the new currencies faster. What are your thoughts on this?.
KuCoin and Binance is both good but I prefer use Binance because of the very very low fee's if you have BNB and Binance have android app and the app is doing good and the Binance withdrawal is a little bit faster than KuCoin
