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?
50 cents is just too small, you can forget about it. It is not enough to pay for withdrawal fee if I am right, on all centralized exchanges, not only Bittrex.
Bittrex announced their service closure months ago and I am so surprising to see you only want to withdraw your money from Bittrex now.
Effective Monday 4 December 2023, all trading activity on Bittrex Global has been disabled. Customers are now only able to withdraw assets as part of the winding down process.
It is the last month, and again I am not sure where are you during latest months and don't know about this service closure from them. You should withdraw your money on Bittrex in November, not wait till now.
