He doesn't prove anything. He also said he was going to reveal Satoshi real identity: as expected, it generated a lot of fud, what I suppose was his goal, because right after a lot of news about it were going on, he just retreated and told he wasn't going to reveal who is Satoshi anymore.
And now there isn't any evidence bitcoin can reach 100k dollars, for me it's just an exaggerated speculation to create more fud and keep he on the crypto trend news.
