Apparently his last post on bitcointalk was in 2011 or so, does anyone know where he went (in terms of the Internet, is he still developing bitcoin or has he left the scene)?
He left on December 13, 2010, 04:45:41 PM
He didn't say any goodbyes or anything , he simply left the forum , you can see his last posts here on his profile => https://bitcointalk.org/index.php?action=profile;u=3
No one know what he is doing , he is probably dead or probably alive , he may be group of persons or group of companies or a single independant person or even NSA
but I still can't put the idea that he trust theymos without knowing him IRL , I guess theymos or other admins here know his real idendity but won't reveal it of course .
