I do wonder if the real satoshi do it for academic interest only and very skeptical of its longterm success.
PS. Apparently the recent price movements were not related to the news about Craig Wright.
The guy has been established to be a fraudster who planted lots of false evidence about other things, and his knowledge of computer science seems to be very limited. Therefore, the evidence that he is Satoshi is likely to be faked as well.
It seems that the main target of his scams was the Australian government. He created a tangled web of companies that closed various "research" contracts with each other, amounting to more than 100 M AUD; and then he used those contracts to get maybe 50 M AUD or more from government research incentive programs. He may have defrauded private investors as well.
He claimed that many of those multimillion contracts were paid in bitcoin; which may have been just an excuse for the lack of bank records proving that the companies had that money to begin with, and that the payments were real. That may help explain why he started to plant clues that he was Satoshi, including backdated blog posts and a supposedly leaked contract with a deceased American colleague that established an offshore trust fund with 1.1 M BTC, to be locked up until 2020. (But there are several other possible explanations for why he wanted to be identified with Satoshi.)
In particular, he claimed to own the 15th largest supercomputer in the world, the largest privately held one. He even gave (totally hilarious) masters-level lectures on supercomputer programming at his university, which included lab exercises with remote access to an "access node" of his supercomputer. He also posted a video on YouTube where he discused his supercomputer and showed an intern working on some visual node management software. However no one has seen that machine, not even a photograph of it. On his company's website there was a letter from SGI that boasted the use of SGI hardware in his supercomputer; however, SGI denied ever having any contact with him or his company, and knew of no such supercomputer.
The final leak of "evidence" seems to have happened when the Australian Tax Office had finally realized the extent of the scam and was about to squash him. It seems that he fled the country just in the nick or time. Recently he somehow got himself invited to a panel on cryptocurrencies witn Nick Szabo, Trace Mayer, and other guys. He spoke via Skype, claiming to be in London with his family. Like the last emails by Danny Brewster of Neo&Bee, that may have been an attempt to divert the ATO investigations to the wrong place...
