So surprised again !
Sometime Bittrex make me so surprised exp delist BitShares BTS , and now BTG
The BTG markets (BTC-BTG, ETH-BTG and USDT-BTG) will be delisted and removed on September 14th, 2018
I think bittrex is doing right thing, no matter reason is attack or paying issue. I hope exchange keeps delisted some scammy or useless coins.
