We all have no idea if he’s telling the truth or not. But even if it’s true, still no one will care. If his purpose of telling it now, especially to the bitcoiners is to lure us in the future like what he did to his old fans before, then he is not in the position to do that or let’s say, claiming about Satoshi is never new to us. Unless if the real Satoshi comes out and defend your claim, which I think is far from possible, we will believe on what this dude is saying.
Just think of the motives why he is claiming this, whether true or not. If you have no other intentions, you will just be grateful that you have met such person. And if you truly believe his ideas, you can take advantage of this market.
Many people have claimed of such, and yet, up until now, Satoshi himself doesn't want to reveal himself. So let's respect this decision and be contented for what we have. After all, we are already reaping the benefits of his invention in this humanity. Also, there's no benefit of this claim, what it would do to the community now? Or can it elevate the btc price level in the market? I don't think so.
