Many of my favorites are exchanged. OKEx is his favorite exchange. But I know Binance exchange very well. The best exchanges in the coin market cap are Binance, OKEx and kucoin, Bybit etc. These exchanges are not only my favorite but also everyone's favorite. However, binance, OKEx, kucoin exchange is the best. These exchanges are very popular. However, if you calculate the number of users, the number of binance and OKEx will be more. I like to trade on OKEx and binance most of the time. If the coin of these two exchanges is traded, the chances of loss are much less. More risk is less. So I prefer these two exchanges.
