I bet one hundred dollars that he was just trying to do it in order to earn the credit of bitcoin, which is almost impossible to realize, or maybe he was just trying to hype the price in order to make people believe in that he is the real satoshi nakamoto.
All those guys are a garbage, i dont know why they really give the enough attention to this kind of guys because we all know the real intentions of this people.
I dont even know why he looks like a dumb guy, maybe it is his body language, or his words, it is really very weird.
More than likely he was involved or even part of the initial creation of Bitcoin and the initial private keys were shared freely as a means to test the system and not considered as valuable as they are now, because at the time Bitcoin was worthless. Think about it. If you are a company that makes locks, you need to test the locks out, so you give the number code to a bunch of people to test it, but guess what? The lock isn't protecting anything so it doesn't even matter than multiple people know the passcode. I think this is why Craig Wright could have signed using private keys from the initial address, however he wasn't able or willing to explain this to the public because they are not ready at this point in time.
