I first learned that the bitcoin creator was anonymous in 2017. I immediately spent the next 20 minutes researching.....
1) -- (2 minutes) A simple google search taught me that "Satoshi Nakamoto" is his screen name on bitcoin talk. He simply quit posting after he finished creating bitcoin.
2) -- (10 minutes) I pulled up Bitcoin Talk and realized it is the same formatted message board I used every day for years for music related purposes. These message boards are EXTREMLY addicting. I'm sure he figured he would simply become a player and get rich off of bitcoin -- never to post again or give away his hand. Satoshi is obviously a computer nerd who is far too bright to be the face of this thing. He (or they) masterminded the construct of bitcoin and posts very methodically. He was aware of the possible implications of being "the inventor" and the backlash which he could face in the future. He also kept 1m coins to always have enough control in case it is ever needed. HOWEVER, what he didn't create was a way to be himself and get any credit for this thing. I mean, he worked for a long time on this and its his masterpiece. He needs to have some type of say/control over his baby. It would be impossible to simply walk away. He of course followed the progress and he would not be able to refrain from posting/input. Find a major player who registered right after Satoshis final post.
3) -- (5 minutes) Satoshi has posted on this page on December 13, 2010. Pieter Wuille registered 4 days later on December 17, 2010. And he has been at the forefront of development. Coincidence?
4) --- (3 minutes) Calculating the chances of Pieter Wuille registering only 4 days after satoshis final post, immediately contributing, and remaining at the forefront of bitcoin development ever since. Coupled with the fact that coincidences simply do not exist. I believe that the chances of Wuile NOT being affiliated with the creator, being the creator, or at least knowing who is responsible for the satoshi nakamoto screen name are fairly low.
