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.
Yes, after the introduction of heavy identity verification and other problems, bitrex lost some of the users)
