It is not the first time somebody claimed to be Satoshi Nakamoto and all of them failed to provide clear proof to convince people that they the real Satoshi. James is another hoax and his alibi is one of the worst even an elementary student use that kind of alibi. His claim has no substance and this means that it is another fail attempt to claim that he is Satoshi.
We don't know who is the real one, unless he proves himself by selling at least 1 BTC, but, whoever he is we should be thankful for his contribution, he is a real legacy and for sure he will be one of the national Hero someday, I know he will show up himself soon, maybe he's not ready yet for now, or he's preparing for some big revelation, we don't know, let's see.
I think he will keep hiding his identity, because there are many reasons for BTC to remain decentralized. and he has become a hero without identity
