On Bitcointalk, I would likely agree it is him. On social media though I will simply believe it is another faketoshi and not. But what will happen tomorrow that will make him reveal himself.
I think this would be the path I would choose for stability. Satoshi Nakamoto has succeeded in concealing this identity for years and knows what it means to Bitcoin, I don’t see a reason why this identity would need revealing. I wouldn’t believe it even if it were to be true, call it self deceit but, it’s one I wouldn’t accept.
OP says if it’s verifiable… what exactly would that verifier be for us to accept I wonder. My best stands on this is, it’s never going to happen.
