Why do people care who Satoshi Nakamoto is/was? It's like wondering the name of the person that created the wheel. Sure, I suppose I would be curious about the name of the inventor of the wheel, if nothing else to raise a beer to them from time to time, but ultimately the wheel is the important part of the story.
Until now, Satoshi Nakamoto true identity is still a big mystery, Many parties want to reveal who Satoshi Nakamoto really is, but true identity can be said to be highly speculative. There has been much debate as to who this very mysterious figure actually was. There are those who assume that Satoshi can be one person or a group of people, He could still be alive or is dead. But without solid evidence, we will never know who the real Satoshi Nakamoto is.
