Poloniex is a good exchange with nice pairs, I use them for years already and I never had any problems with them. I use binance too, they are the biggest one and like that they have some advantages. I`m registered on many exchanges because it`s a must if you wish to make profit, every exchange has different fees, different pairs, and in the end most of all depends where you live if you wish to withdraw fiat from time to time.
