For the small ICO token that i got from bounty campaign and doesnt really have a good prospect in the future, ill prefer etherdelta or forkdelta to fast selling. but if the ICO token is really good, i hope they are listed in the bittrex, kucoin and binance. for the biggest crypto like Bitcoin and any other big alt coin like ETH i prefer to use binance and bittrex. for the conclusion i really like Bittrex at the moment, the withdraw and deposit time is fast enough better that the other, the website design is eye catching.
