According to Satoshi, in his P2P profile, he is a 39-year-old Japanese man. However, this information is uncertain and there are many hypotheses about this character as it is not sure whether this name is the real name of the inventor or just a pseudonym for this person used only to announce the new currency. It is also not known if the name was for a man or a woman or for a group of persons. On several occasions it has been announced that the identity of the inventor has been revealed but these ads have not been confirmed and the real character remains unknown to date.
