Shinichi Mochizuki aged 53.
On the P2P forum where Satoshi Nakamoto surfaced, his bio says he's 47 from Japan.
Of course that means nothing.
Satoshi was so elusive he used to create a new BTC wallet for every block he mined, said to be 22,000 wallet addresses. Probably part of testing. He's said to have 1M BTC.
Bitcoin's Genesis wallet has 68 BTC to date. People send small amounts of Satoshi to that wallet with notes, probably hoping to get a response.
Maybe he isn't Japanese, or maybe he is cause he's real slippery anyway.
Martii Malmi worked on Bitcoin with Satoshi. Supposedly not even he knows who Satoshi is. Maybe Satoshi is his sock puppet. There are a few other geeks who worked with him. Some components of blockchain technology is taken from Bittortent, granted it's P2P nature, but I don't know much about that stuff.
Creating the first digital store of value, could've potentially put one's life in jeopardy.
