Hey,
Also got stuck with this shitty exchange.
I had BCPT tokens on Binance and when they delisted the token (and made it crash BTW), i moved the tokens to the first exchange listed on CMC by BCPT volume: sHitBTC
I could convert the BCPT tokens to XTZ (I chose Tezos to move back these new tokens quickly to Binance with low fees), but once i transfered the XTZ tokens from my trading account to my main account, i had the bad surprise to discover that i could not withdraw XTZ tokens, nor move them back to my trading account to convert them to any other token that's working according to their system monitor page...
The fact that you can only move tokens from trading to main account and not the other way round is clearly suspicious and made to lock your tokens without no possibility to withdraw them.
I opened a support case one week ago but still no reply and XTZ withdrawal keeps being in 'technical maintenance'. I guess they're stuck there for a while...
