I'm not sure what's more stupid, sending $80k in one go to a service that is clearly illegal in the first place or trying to get it back. He can't even go to the police, what's he going to say? Oh, I was trying to launder money through his service and he scammed me! It's fine to put the information out there and hopefully people will stop using his services, but it was bound to happen.
Well, he can and will go to the police. He wasn't doing anything illegal and how is mixing coins illegal? He was trying to mix them so that they did not link back to him. Bitcoin is supposed to be anonymous, but as we all know that if you see my donation address below and can link an address to me, then it is no longer anonymous. So, if I had coins, that I didn't want linked to any of my "public" addresses, I could "mix" "clean" or "launder" them and that should mean they no longer would show my donation account linked to any coins.
I agree with you about sending 80k in one shot, that was the mistake. But we can't just allow Moriarty to steal it.
So I grade you an F as far as this statement goes...
"I'm not sure what's more stupid, sending $80k in one go to a service that is clearly illegal in the first place or trying to get it back."
Clearly the answer is a) sending the coins there was far more stupid.... but that said, you are saying now he should not try and get them back? That's insanity.
