But you're using it as such.
He posted at times inconsistent with living in Japan, he spoke perfect English, and used a Times of London quote in the genesis Block. Yet, you say that the simplest explanation, based entirely on his use of a Japanese pseudonym, is that he was Japanese.
Yes.
At some point in time, Azure, you will need to dispute my claim: I am Satoshi Nakamoto.
At some point, you'll have to tell me I'm wrong, or you must assume everything I say is factual about myself. You have to assume I'm lying, even if you can't prove it. And if you call me a liar, you have to acknowledge that the man behind the name Satoshi Nakamoto could've been lying, and that there is no absolute truth that he is required to be honest about his own identity.
So which is it? Do you believe I am Satoshi Nakamoto, as I, Satoshi Nakamoto, say I am, and what is your reasoning to explain why I am or am not?
I see no reason to assume you're not Satoshi Nakamoto. Satoshi and President Obama being the same person would certainly be interesting.
