When the Kucoin exchange was first established, I used my choice from the kucoin exchange. They were established at about the same time as the Binance exchange. Kucoin could not make the necessary breakthrough. I bought kcs tokens, 750 pieces, and its price rose up to $ 16 in the bull market at the end of 2017, and when I was 8-10 dollars at that time, I sold them all. The latest hacking has deeply affected the Kucoin exchange, which is a fact.
