Well for me, KuCoin is one of the Best Exchanges in trading. I'am so happy if I have hold a cryptocurrency that is listed in Kucoin because I can say that the currency that I'm holding is real and legit. But I'm not a fan of Kucoin but I also hope it will be the number 1 exchange site.
Indeed, this is so, KuCoin is one of the best exchanges at the moment. I, too, am not a fan of this exchange, but I'm just trying to soberly evaluate based on personal experience and reviews of other people.
https://revain.org/exchanges/kucoin - here KuCoin has a good rating.
https://www.trustpilot.com/review/kucoin.com - in this site is already worse reviews. I dont know why so. But in general, it seems that there are much more positive reviews. I believe that the opinion of ordinary people and users is the most valuable and gives the most objective information about any of the exchanges.
