Earlier quoted context omitted.
Craig Wright being Satoshi is unpopular opinion in the Bitcoin community but I think there is a good chance that he is indeed Satoshi or that he was a leader of Satoshi group. I did some research on him and his past activities, and the things that I found on the Web and on the Internet Archive are somewhat compelling. I will write it up sooner or later as a blog post(the clues that I found).
I could buy that he's a straggler that was left to "muddy the waters" in search of the "one true" person (or group). Would be interested in links to the most personally compelling evidence (in either direction), for those reading.
Search for Craig's blog posts and computer security newsletter groups where he was active 15-20 years ago; he talks about P2P networks, hashing(Craig discusses how SHA-1 is vulnerable and not secure anymore), statistics(Poisson distribution, the same statistical model that was mentioned by Satoshi in the Bitcoin whitepaper).
I found some tids and bits that he and "Satoshi" have in common, plus Satoshi used British English and Craig is an Australian. All of this means nothing but either Satoshi is dead or this Australian guy has something to do with Satoshi and Bitcoin because he wouldn't be pushing so hard as Satoshi persona if he was't involved with Bitcoin in one way or another.
Craig also said couple of years ago that he will share his bank statement of him buy the original bitcoin.org domain but he still didn't do it. Again this would be indirect proof but Satoshi signing his private keys won't be happening anytime soon(and anyone can sign keys if s/he steals them, again indirect proof).
