Hi
I just download binance exchange from play store and i feel that binance is better than bitrex,what is your opinion
Thanks

I share your oppinion.
It is especially nice that binance credits you with many forks and sub coins.
E.g. for holding NEO you earn GAS, but not on Trex (as far as I know), while binance credits it.
bittrex has nothing speciality like binance I am trading with bittrex from a long time. but other then I don't find any issue myself. bittrex is pretty good exchange.
but if you talk about support non of them is good.
