You research looks interesting. I thought they already found the guy, it is an Australian engineer. However, does it really matter who Satoshi Nakamoto is !?
Does it matter? No. But it is satisfying curiosity.
Does it matter what the motive was behind the Las Vegas shooters rampage? No. But everyone is very interested in that which will have no bearing on what already occurred.
People want to know. That is part of life. Without curiosity, we probably wouldn't have made far from the cave.
Wouldn't it be cool to talk to the person behind bitcoin? How did they piece it all together? What motivated him in the beginning? What does he think about the state of the crypto currency realm today? Does he really have all those Keys or are those bitcoins lost forever lowering the overall bitcoin total distribution?
