Bittrex is amazing, and is one of the primary reasons I discovered Steem.
I must say I agree with Ned in that it must be technical problems, I doubt there's any ill intent on their part, nor do I doubt they have to steal 1250, as they get 0.25% for all transactions anyhow.
Though I do understand it can be annoying to have your funds locked up, so I feel for you there.
