KU? Where on earth did you see that in his message, and what has something related to that is the Kucoin that he mentioned, and he already stated it that it is an exchange, and yes, Kucoin is really a wonderful exchange also like Binance exchange and other great exchanges that are in the market. They have very attractive user interface which is also very friendly to many of its users.

I started using it just like a month ago and all the services that I have enjoyed through them is really great. Sometimes, it seems to me like they are fortified with good luck charm lol, because since I am been using them I have been making profits more than losses like other exchanges I have been using to trade. I think this exchange would really be suitable for the US citizens.
