satoshi was chased and killed by a government agency a while before bitcoin became popular, he managed to destroy his private keys before this, reason why you will never see that coins move from blockchain.
he did this not because of the economic value of bitcoin but because the complete purpose of his currency would lose sense in the wrong hands (exactly the situation we are living today, where bitcoin is becaming just another currency for banks and wall street idiots)
Actually, I heard that Satoshi is actually a neo-samuri. In the year 2156, the Yakuza will have risen to global domination. Without getting into too much detail (it's 142 years for Christ's sake) suffice it to say, China and USA take each other out financially, and Yakuza gains strength in the East finally bleeding into EU and demonstrating its power with a new holiday kind of like the Purge movie.
Meanwhile, a long forgotten splinter cell of Yakuza, unhappy with the direction that the NWO emporer is taking the civilized world, rebrands itself as the Neo-Samuri. It relocates itself to the former USA and establishes a thriving underground stronghold using the cover of the Church of Latter Day Saints to recruit members and teach everyone how to tie really good knots.
For decades, the Yakuza had been using North America to test social, technical, and biological experiments before deployment to the rest of the world. It was there that they created YHJ-43589, the first complete genetically synthetic human being derived from primordial soup. They had been successfully creating livestock for food in this way for decades, but the human brain eluded them. Resources waned for many years down to a single lab. When YHJ-43589 had been born, it was just a footnote because the Yakuza authorities fully expected it to grow up trying to chew on grass or peck grain like countless others before it.
When YHJ-43589 showed promise a few years after its birth, a lab tech was so excited he got drunk one night and started telling everyone what he was doing and how a simple pheromone extraction from an extinct ant was the key. The Neo-Samuri used this information to their advantage, and pressed the lab employees into making humans for them. It turned out that YHJ-43589 wasn't just smart, it was a fluke. YHJ-43589 was so brilliant, it figured out a way to tweak the human brain to its desire. It desired change. It desired Satoshi Nakamoto.
On February 11, 2186, Satoshi Nakamoto is born. He can predict 10 minutes into the future. At age 6, he uses chicken wire and parts from an old Sizolo machine to create a long range encrypted transmission device that the Neo-Samuri use liberally. He dislikes cauliflower.
Satoshi was so brilliant that he would often argue people in circles, convincing them that they won his arguments. He chose to walk to school instead of bringing his own lunch. By the time he was 12, he had discovered time travel. He was the perfect double agent, but he had his sites set much higher.
He was brought up to live the Neo-Samuri way. Forced by the Yakuza into slave labor, he was forced to remove fly feces from pepper shakers using boxing gloves. He desperately wanted a country for his people to call their own, and realized that he needed money to fund a full blown revolution.
On February 16, 2212, A fresh 26 year old Satoshi Nakamoto traveled back in time to create Bitcoin. The reason we don't hear from him anymore is because he went back into the future to spend his bitcoins and wrestle a small part of the world from the clutches of an evil empire.
