lease add bittrex to your complaint, they froze accounts without warning and changed terms of service requiring kyc for withdrawals without any grace period for existing customers.
Poloniex and bittrex are both rogue exchanges now, and both should have their actions tested in court.
I have no problem using bittrex. I have been using this exchange for a long time. Perhaps your problem is due to the fact that bittrex added to the auction dollar? Support on this exchange really works bad but it is a problem of all exchanges. Poloniex really has a lot of complaints from users for a long time so I left this exchange and I'm not interested in its future. I hope all users will pay attention to these signals and leave it without loss.Poloniex and bittrex are both rogue exchanges now, and both should have their actions tested in court.
