Well in a group where I'm reading daily signals they mostly talk about binance but for me bittrex and poloniex are still a better choice for me. I've used yobit before and I'd dealt with no problems to me, so sometimes to these three exchanges now I'm circulating. In wherever I have my mood of doing my trades, I'm going there since not all of them holds our preferred altcoins. Some do have it and some of them, they don't have it.
