Be careful with bittrex if you are an unverified user. They just dropped their withdrawal limit from 1BTC to 0.025 BTC without warning.
It's time to switch to
https://cryptox.plNo limit, very low fees and nice GUI.
When trading bots are active, prices are similar to Bittrex.
I'll give it a try next time I have something to trade. It doesn't help for the ~4 BTC I have stuck on there right now though, 4 withdrawals has tuned into 160 withdrawals without sending them some identifying information. It just seems rude not to give clear advanced warning, I may have even verified if they had given a reasonable argument as to how they will be responsible with the information (last time I verified on an exchange my identifying information was leaked publicly and I am just having none of that now).
