Time for the scammer tag.
I think that after the recents hacks on the website, the webmaster told himself "fuck it, I'm gonna steal from my users too".
Bitcoin value decreases when you do that. That's no good.
You have no idea how much time I've spent to help my users with these hacks (which were not compromises of Bitmarket security). And I didn't get anything in return. If I wanted to steal the money, I'd just announce that I got hacked and whole wallet was stolen. But I want to be completely honest with my users. That doesn't make the funds magically appear, but I believe it's the right thing to do.
