Binance is much more better than bittrex, bittrex has a shitty support and they are never going to reply to your questions. The best thing that you can do is just start trading on binance or bitstamp, they both are the best exchanges out there.
Actually i never have question so far about bittrex service so i dont ever facing the problem about support of bittrex.
However, if you said binance is much better than bittrex, i think i should try binance too.
