Online petitions do absolutely nothing, and they've been around since the beginning of the internet.  That's the wrong route to go.  Contacting some branch of law enforcement in China (or wherever Livecoin is/was located) is probably the only reasonable solution to recovering your funds, assuming Livecoin doesn't fix this themselves--and my gut is telling me that not only aren't they going to do that, but that they're responsible for this mess.  I think this is their exit scam.

F..f..f..f..uuuuuck!!!  I'm sorry to hear you got burned, bro.  I'm grateful that I just happened to get lucky, but chances are that had I made one more deposit I would be in the same boat (albeit with less money lost, since I never trusted Livecoin with anything more than like $40 at a time).

This sucks for everyone who got burned, don't get me wrong.  I feel badly for everyone who had money there, and I'm hoping at least some of it can be recovered somehow.
