i believe he is still alive and probably he wont come out to the public because he is scared to get hunted by scammers and criminals that will be after his bitcoin wealth, although i believe that one of this admin/moderators are the actual satoshi nakamoto but of course he wont still admit it. but i guess that it is  much better if he can just reveal himself to the public so that the president and governments will honor him as a hero and thank him properly for inventing bitcoin.
