Really I kind of find it hard to believe what people are saying bittrex is a USA based exchange if they were commiting fraud and stealing money they may get away with it in the short term but long term this is america nobody gets away with that type of thing on that scale and that in the open for too long. I really thought they were one of the most trusted exchanges?
They got my $30 - what am I gonna do? Support stopped responding after a while and the only other venues of communication are: an address of the shelf company they hide behind, or their law firm. It's not worth doing anything, even in a small claims court. And I was one of the suckers to actually submit KYC docs. Most people wouldn't even do that and just forfeit small balances. So yes, they can get away with this shit for a long time.
Even folks having problems with $10k would have a hard time in court. Try explaining a TX ID to a judge.
