BIttrex doesnt support hardfork, stakes, airdrops, tokens from ICOS... the exchange get the tokens, but you don't!!!!
as long as i discovered i wasnt getting GAS for my holdings of NEO (but bittrex sure keep holding the GAS that should have been assigned to its customers ).. i moved from bittrex to binance.. now.. bittrex never again!!!!!
Binance support forks, airdrops etc?
of course.. binance is a serious exchange,.. they give to their customers, what belongs to their customers! nothing more, nothing less
