the short answer? no.
no one is successfully going to class action Gox. Bitcoins aren't real. What are they going to cry to the government about, a missing computer hash?
not to mention, the governments have been warning people not to buy it for a long time. Bitcoins don't exist, they're not recognized as currency, so nothing was stolen when you bought "air" with your real money.

so binary data that forms music, which then gets stolen by people pretending they made it. has never led to court cases?
or that binary data that forms movies, games, software......
oh and lets add some more insight... pirate@40 got arrested in relation to bitcoins.. Shrem also got arrested. so i dont think bitcoins are imaginary.
and if bitcoins were imaginary. then why are you here writing messages about something that does not exist. why waste your life on a topic you do not believe in?
