It has already been discussed a lot of times over here, and nobody knows who can he/she really be, because the only thing that we know is that he was the real founder of bitcoin, but nothing more than that, and yes, that he was the founder of this forum too, but then he left this forum and we have never heard about him again. But if he decides to show himself, i doubt that people will believe that he is the real satoshi nakamoto, because a lot of time has passed since bitcoin has become so popular and famous everywhere.
Satoshi Nakamoto is a very mysterious man and nobody knows the exact reasons why he left something that he worked hard for and that is now very valuable. He could have been one of the richest man alive today but then again we can only speculate or guess because only Satoshi can really answer the many questions surrounding his real personality and the details as to where he is now...that is assuming that he is a single person and that the name is not representing a group. The story behind its founder is actually adding more mystique to Bitcoin and putting more magnet for the mainstream media to pick up on.
We have many things that we need to thank Satoshi Nakamoto for. Just take this forum which has been serving well the Bitcoin community for many years and have become like the beacon of light for all of us. This forum has been a big blessing to many and right now it is a big source of revenues for the group of people administrating it.
Hope that one day there would be a full disclosure as to the details of Satoshi Nakamoto and maybe it would be good if those details would be coming from him personally. We are looking for that day.
