So, here's the deal. In the first of the two-excerpts-from-the-book, Mr. Nakamoto criticizes himself, that despite all the means of anonymization, he still got caught on time zones when he made messages on public pages and forums. It turned out that he was broadcasting from the east coast of the USA. I repeat, this is not my "find", he wrote about it himself. He also writes that he was an IT lab assistant at some institute, and his mother was an unpopular writer (judging by the information, I will be even more popular, lol). And at the time of the creation of Bitcoin (2008-2009) the kid was around 20-30 years old.
