First: I'm a U.S. resident. That limits the Crypto exchanges I can use. No international Binance or Kucoin for me. Second: my favorite Crypto exchange is Binance U.S. Great rep and very low fees if you use the native BNB tokens. But there are several varieties of Crypto that I trade on OKCoin. Why? Reason #1: Because I'm small-time, dealing in relatively small values of Crypto, and OKCoin allows you to trade in values of Crypto that are much smaller and much more precise than Binance U.S. ReSee full review
