It's good to see Ryan X. Charles stand up for what he believes.
IMO the reason CSW can't sign anything with the Satoshi keys is they were destroyed. It's reasonable to suspect that he has time locked transactions for unlocking the Satoshi hoard.
or he never had the keys to begin with and he is just another sociopath, pretending to be someone he is not. Ask him to code "Hello World" with pen an paper.
Could be. It's a mistake to assume that his lack of programming skills indicates no involvement in the Satoshi team. It took much more than good programming skills to create Bitcoin.
