It is a bad exchange yes, but also is it even worth selling at these prices? I don't know when you bought but you are most likely at a siginficant loss.
I don't even know how you even got to deposit your BitClave. I think it has been several weeks that Bitclave deposits were halted. It couldn't be a techincal issue since it's an ERC-20 token, it must be some internal dispute between HitBTC and Bitclave team.
No I didn't deposit any Bitclave there. They had a dispute since the beginning because HitBTC listed Bitclave futures, which represent promises on tokens if you buy them on their exchange. And that happened way before Bitclave launched officially.
