The theory that this person came up with is very interesting especially the initials of S and N which as you can see it is the same with sstoshi Nakamoto. I don't know what that person will say or reply if we ask that person to prove his theory that Nick is really Satoshi Nakamoto. It is also doesn't make sense if Bitcoin is created for the purpose of having anonymity then leaving initials defeats the purpose so I don't think that nick is Satoshi himself. If Nick can access the email that is used in correspondence with siriud then i'll believe that it's him.
