People should jot deceives themselves to think they can conduct a research that could let them know about Satoshi Nakamoto. Satoshi can be a group of individual which is what I am think. Sotishi can be a single person.  But to know this, it would be when Satoshi proves himself to be Satoshi. I do not know why people are so much concerned to know who Satoshi is when Satoshi do jot want to let people know him which is one of the reasons bitcoin is different from all other coins.
