I am agree with Binance and Kucoin, but Bittrex ?? Are you sure ??.
As i know Bittrex is a big exchange but when IEO war started the first time IEO in Bittrex is fail.
Bittrex now become a mid exchange, not a big anymore.
yes I didn't see Bittrex on the big exchange board. Previously Bittrex had a large trading volume, but now binance dominates trade.
this is the reason why Bitrex failed with its first IEO. he lost faith.
