If the goal is to convince people that he is Satoshi, and he really was Satoshi, this would never be his best choice of action. Given that goal, what conceivable reason is there to delay this simple action?
The most probable conclusion is pretty simple. I'll cop to hedging a bit with "probable", but in the event that this claim turns out to be true, it would be fair to ask questions about why on Earth this was considered to be the correct way to prove the claim.
Or he could be a lying douchebag who's assuming that he will be associated with Satoshi in the general public consciousness after the media gets bored of the story and expects to profit from that.
I have to admit, it would be awesome to see this as an elaborate way to get send a "fuck you" to all the people that accused him of fraud initially, when he claims we was trying to just lay low and let it pass. It would be the most elaborate trolling ever carried out.
Then, as Satoshi, who is the founder of BitCoin and owner of quite a lot of them, who must be quite intelligent to be able to have created the system in the first place, he must also be quite colossally stupid and bereft of self-interest to not realize that proving the founder of BitCoin deliberately generated that much drama is likely to significantly negatively affect his substantial BitCoin holding by making a lot of people reassess the stability of BitCoin if the creator is suddenly proved to be this drama-prone.
We must also hypothesize a very rapid flip between someone who has successfully hidden the identity for this many years, the very definition of Minimum Drama, suddenly flipping to Maximum Drama.
It's not an impossible theory... which I mean, it's not impossible, and should it prove to be true, I won't apologize for this analysis because I think it'll still hold.... but it's an awfully precise one.
AAMOF, in yesterdays post, he talked about crypto, but he did not claim it to be proof for anything. Today he is announcing proof for the next days. We'll see...
In the event, such proof is not merely absent but has been shown to be falsified, which is both dispositive of bad faith on Wright's part, and totally in keeping with his own reputation. He's a con man. This is a con. What more do you need, a couple stone tablets and a mountaintop?
No he has appeared in person and confirmed the story.
