Binance and Bittrex for me it's a good and the best among the others. This both exchanges will definitely good to me. Binance is the highest according to the statistics and I have more faith and to trust for the both of it.
Actually, these are top notch exchanges that you have mentioned, and we all expect that since most especially the likes of bittrex have been able to stand the test of time and have been doing well for a long time now, keeping on with that will help them sustain themselves for the long term. With volume, binance just came all of a sudden to overtake a lot of exchanges, and so far is doing great. For exchanges with nothing to really come with to stiffen the competition, it will be hard for them to thrive and over time, with less volume, they simply become crap.
