He,She or They.No one knows on where is Satoshi.We wont able to know if he would came back into this forum but one things for sure if hes still alive that he do visits this forum.
We might not even know that he's just posting using other new accounts and lurking on the forum he made.Lots of satoshi talks ever since but we cant even see a glimpse of his shadows.
Maybe he is one of newbies who are very knowledgeable already about crypto currency and in the forum as well , or anyone else but wherever he is , the name Satoshi were in the bitcoin forum always and forever , that's one thing which is very sure .
