These are no doubt good exchanges in crypto, but for me, I don't need a lot of exchange as I am already satisfied in using one exchange.
Currently, I am trading at Binance and I have the same satisfaction that I have before, and mind you, I also invested on them through their BNB coin.
I think Binance is more than enough for investors and if you have decided to trade here, you will feel different from other exchanges. I was trading here when this exchange was just established and of course I also made a lot of great profits. The coin that I feel best to hold is BNB because holding this coin helps me to reduce transaction fees or can use BNB to participate in some big IEO projects.
