KuCoin has a very good interface and a nice selection of coins. Visually, the site is amazing. The customer service is terrible, and they do not offer a live chat support on the site. If you click on support you are directed to a bot in China I presume, and will get a response in Chinese. The withdrawal times are horrific, and they appear to not be able to handle volume. Also, in overview section, the reserve assets are confusing. Trying to sell and withdraw are awkward. I think they had potential to be great, but these issues kill it for me. Fail!
Kucoin is my favourite exchange. It's friendly, colourful and professional. I love how you can see the prices in your own fiat currency as well as in BTC, Ethereum, USDT and a couple of other trading pairs. If you buy some of the Kucoin shares coin you can share in the exchange's profits, which would have been nice to do when KCS was only 70c. The more KCS you have, the more you profit. I also love that you don't have to undergo a gruelling process to join. It's simple and easy, like it should be. Kucoin is excellent!
Pushing what an exchange should be! I have not used customer service but I see they have a live chat option Couple of tips:. If you buy the exchanges kucoin you will get discount on transaction fees and you also are paid a daily dividend for the kucoin you hold. Passive income in a win!
