No he is not. Many people that know the real satoshi have said that they know the way he talks is nothing like the original satoshi. The way he portrays himself doesn’t seem how satoshi would act.
Can't argue with that.
He had many tries to provide some proof but he always made some excuse . It’s very easy to prove. Just sign one of the early blocks and everybody would believe him but he can’t even do that.
He wouldn't even have to do that. He could just post to the forum here under his username. And say he was craig wright. And that would settle that!
