By the way, how you would decide his statement is true or not? As I understand, there is no definite way to prove that someone is Satoshi or not.
You missed the good odds. When they first released the market, it was something like @2.5 for YES, @1.5 for No, but since Craig Wright posted that he isn't going to prove it on his website, the odds dropped down (obviously). I bet a bit too late, and got @1.37 odds for the No market since my deposit took forever to confirm.
