What I can say is that if Craig Wright claims he is Satoshi even though he is not, let him sign a message from the various Satoshi Bitcoin wallets holding the Satoshi Bitcoins.
Would't have to see his court case when the very system he supposedly invented gives him a very straightforward way of proving ownership of those genesis wallet private keys and he has refused to do so, but unfortunately, he doesn't own any key of those genesis wallet, likely probably will face jail time.
But Fakesatoshi scamamoto is very good at faking a story (or a story teller) about why Satoshi choose a Japanese name, instead of being english person when is not supposed to be a Japanese person.
Why satoshi kept Japanese name by craig. To be frank he is not really as wealthy or even rich as he is acting, this is among the reason they knew he is not Satoshi because he can't even accessed the Satoshi address with a million+ bitcoins. He is far from being consider among the wealthiest bitcoiners.
I firstly heard about this guy was in 2015 end or mid of 2016 something (didn't remember the actual date) but the price of btc was not much high during that time and probably i wouldn't say Craig is poor perhaps holds bunch of bitcoin in couple of multiple different wallets till this date. Also, afaik craig was among those people much intrested in forking bsv years ago and here is the link
said btc won't reach 100k ever, and what most i dont like about him is "a fragile ego" dude pretends to be satoshi and criticize bitcoin that bsv is the orginal vision of satoshi will fulfill the original promises being p2p cash system at a same time.
