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.
I have been using Bittrex for a long time. I have also tried using their support and they answered me. The difference between Bittrex and binance is that Bittrex has already been proven for a long time already. Binance is very young, although the promotion is really good that it became famous in a short span of time. But in terms of support, Bittrex users far outnumbered binance's users that is why you will have to wait for a little while before their answer comes.
