According to the sources from red.it, satoshi NAKAMOTO is a real person and  there he confessed that the name he is using is a pseudonym, he will reveal his identity sooner but for now he is a real person and the only owner of BTC. According to me, he is not revealing his identity to anyone because everyone knows that BTC is not legalized by almost every country and if the people knows about him, then he would be surely interrogated by the officials of the respective countries but he is real and invented such a boon for the human welfare.
