I have sent countless messages to Steve simply asking for more information.
He has never replied to me, as we all know he does visit this site on a regular basis, so he is obviously ignoring us.

As for legal steps, you can count me in, but I would be happier to hear what a lawyer would have to say regarding our realistic option(s) before we move forward. They might suggest some other avenues, so there would be no harm in just asking a few questions first.
In my country you can see a lawyer for free the first time to get an idea of what you can/cannot do next.

Realistically, all money recovered would probably go toward paying for the lawyer, but I would be happier doing that rather than Steve profiting.

I think, (in a small part), for the future of Bitcoin we also have to prove that this is not a currency where fraudsters can just get away with blatant theft like that.
