Just wanted to say this thread has been very carthartic. I did a 2000 Doge test, which was successfully doubled, then went in for 10,000 Doge which I lost. I know its not much, but I just started mining in february (and only with a single r9 270) so its a significant portion of my total cryptocoin stash. Also wanted to point out, with so many people saying how they were stupid for closing it down so soon, maybe coin2x was the only one who WASN'T being greedy.
Good luck trying to get police involved, I personally think that's a waste of time. Can't remember it exactly, but they even had a disclaimer on the site regarding 'past performance is no indication...blah blah blah', so there probably isn't even anything illegal here. Come on, we all knew this was too good to be true, right? Only way you could have come out ahead here was to invest early, then reinvest your original amount or a bit less.
edit: And one more thing...how much you wanna bet coin2x (whoever he/she is) is probably reading all this for one last laugh?
