How many of the people named Satoshi Nakamoto have a background which perfectly fits being the creator of Bitcoin?
How many of the people named Satoshi Nakamoto have a family that believes they could have created Bitcoin?
He probably used his real name because Bitcoin started off as more of an academic exercise than anything. He felt anonymous because he was posting on an obscure online forum like Ross Ulbricht did.
There is no way he was thinking Bitcoin would go beyond an academic exercise into a global phenomenon that turned him into a global celebrity.
As for the age thing, how many 40+ year olds do you know that jokingly say they're 38 or 39?
The ridiculous denial of people on bitcointalk, trying to protect their creator or whatever, is pretty hilarious.
The guy is 64 years old and lives in the wrong time-zone. Satoshi Nakamoto like lives in NYC ( read: http://en.wikipedia.org/wiki/Satoshi_Nakamoto ). He is likely British and reads the UK Times ( Chancellor on brink of second bailout for banks ). He probably is likely involved as a software developer in the financial industry. Probably built Bitcoin when he got laid off during the financial crisis in 2008.
