I have had a little money stuck with them since they banned US customers to the original site. There has been absolutely no way to transfer the money out of my account, even to Binance US, and I eventually had to just call it a loss.
If only I had thought of that.. Unfortunately, you were only allowed to convert to the Binance coin. That option did not work for me, I can't recall what the specific issue was now but I am guessing had something to do with KYC.
Unless the exchange has collapsed you should be able to withdraw crypto and cash it in at Kraken or wherever.
