So I have like 50 cents in assets and obviously cant withdraw. And dont want to pay like 20 bucks for their "administration fees"
what to do now?
Bittrex filled for their bankruptcy and I highly doubt that your 50 cents will be withdrawn without paying the fees required.
Just consider it as a donation to bittrex, it is obvious that the fee are more than the amount you are withdrawing. I personally think that it is not worth to fight against bittrex for that kind of amount, it will be a source of stress for you seeking for some empathy here.
