What is the crime?
Where is the jurisdiction?

I think civil cases allow you to receive damages.  At least in the one criminal case I was the most associated with, I could not seek damages and was told by the prosecutor that damages were a civil matter and his office was not allowed to offer help.

If there is a lawsuit, my impression is that it should be a civil matter.  It is also my impression that you should be able to state what you desire as an outcome and it has to be something that the court can grant or you are wasting your time dreaming about it.

I think that the best shot that I have to see my money again is for Roman to get settled, gain some liquidity from a venture capital guy, and re-open his exchange.  My impression is that other people would like to thwart any efforts that he might make to operate an exchange.
