Fuck, man. Sorry to hear it
It's not as simple as that.
I tried to withdraw the 50 coins I had at Gox to a paper wallet a year ago when it became obvious something was fishy there.
They wouldn't let me withdraw without identity verification so I went about acquiring ID (I don't live in the kind of fascist regime that requires citizens to carry ID) and by the time I got it together, my 50BTC had already been "withdrawn" by someone else.
Needless to say, I immediately opened a ticket but was given a runaround for dozens of emails over several months until they finally imploded and I haven't heard from them since.
Luckily they represented less than a third of my coins at that time. At an average cost of less than $120 they still represented a significant loss but I was still firmly in the black. When the price broke a grand, I was furious at the thought of losing $50,000.00.
Of course I joined the class action lawsuit but I'm not holding my breath expecting anything back.
Sometimes shit happens.
