I don't know and in almost every news when someone claims he is Satoshi Nakamoto I am never interested in reading or finding out the truth, because I think it is not important to know whether the claim is true or not.
People who appear and claim to be Satoshi Nakamoto certainly want to gain popularity and it could be that he has his own agenda because he knows how popular this coin is and how many people are quite curious about its creator so that when he claims he will probably provide more profits when he does another thing in the crypto world, because we know the crypto world is filled with many fraudsters and the way he cheats is by starting to build trust from this large community.
