possibly sending bitcoin from the earliest possible wallet, which I think is the coins generated in the 1st block after the genesis block. I suppose it still dosn't prove identity, but it would be pretty impressive.....
It would definitely add to some credibility, but I would prefer that Satoshi didn't move any of his coins.
If he did that, it could cause unknown effects on the bitcoin economy that may be irreversible.
I do not believe the real Satoshi Nakamoto would want to destroy users investments and his experiment.
If Bitcoin/bitcoin should fail and die, it should do so on its own merits, and not by the creators hand.
Such an intervention, to me, seems counter to what Satoshi created Bitcoin/bitcoin for.
Craig Wright has purportedly made statements that he: "wants to take control of bitcoin back".
...
If Satoshi registered that domain himself,he must have given his personal info to domain registrar (a prerequisite to register any domain).Does it means,that domain registrar has information about Satoshi?
Satoshi most likely used a VPN and TOR.
In addition, he used an anon website registration service, see Theymos quote below.
