My Theory:
He is a quiet guy who reads stuff like bitcoin twitter all the time.  He and another guy who is local with him may have created the experiment.
This guy had access to the real Satoshi and likely interacted with him at school.  This Satoshi Nakamoto is the guy everyone is looking for.  The real one, who is hiding behind this online persona of the actual programmer friend, is the guy who wrote the early series of emails and is responsible for inventing Bitcoin.

Why doesn't he come forward?
He simply doesn't want to be associated with the name.

Doing some analyses of the early emails, the language appears to be incongruent.  Which supports the idea that he is one guy hiding behind his programmer friend's name.

I would say that if he were to be found somehow by some random person that he would run away from them or maybe confront them.  Extremely unlikely he will be found.  Likely nil.  Probably are traces of him on the Internet if you look hard enough under his real name, but most likely its been deleted.

Satoshi is anynomous. He may be lurking between us

Everyone knows Satoshi Nakamoto was the first to discover Bicoin but it could be just a pseudonym or the name of a group is still a mystery. I read a lot about satoshi but all are just assumptions with no clear source.

The name of the creator is actually known, which Satoshi Nakamoto... the debate is whether that's the real name or not.
I think lots of matured, intelligent, serious & cautious adult wouldn't use other people names as theirs. Children would make such mistakes more.

Satoshi Nakamoto is a person who creates crypto-based digital money, Bitcoin.

In 2008, Satoshi Nakamoto published 9 sheets of 'white paper' which for the first time mentioned bitcoin digital money. Peer-to-peer electronic money or maybe it can be called an electronic system of mutual cooperation.

A few months later, Satoshi Nakamoto released the Bitcoin software for the first time in partnership with online developers and coders to prove it to the public.

Raymond Reddington says he knows Satoshi Nakamoto in The Blacklist 

If i'm being satoshi, i will do the same thing like he did. I can buy everything with that money and just playing everyday and watching my son grow without worrying about money and media, what a beautiful life it is.

We are still wondering who Satoshi is. It doesn't look like we will learn about it. I say "it" because we don't know if Satoshi is a human or a group. I don't think that we will ever learn about this.

Right Satoshi Nakamoto is a person who invented bitcoin, implementing the first blockchain database and he is born in 5april 1975. He is from Japan (nationality).
