I stopped using Bittrex a week ago when I realized that it lowered my daily withdrawal limit to 0 for no reason. I have been using Bittrex since more than three years and from one day to another it requires me to do enhanced verification. Luckily I only have coins value around $120 on the exchange. In the past, Bittrex was one of the best exchanges, but that was once. One can only hope that decentralized exchanges will be ready for application soon. I won't trade on Bittrex anymore.
