This law firm represented victims in a cryptocurrency class action before. Maybe they would be interested?

Nice. I've also talked to a lawyer friend locally that claims could get their firm's services discounted. Personally I'm hoping that amount up for identification bounty is enough to cover filing the suit and issuing the subpoena to get the identity. Beyond that continuing with a civil suit probably doesn't make sense but then there's the criminal Internet fraud route.
Would someone be willing to contact the above firm? I'll see if I can get a price out of my friend.
