Nobody seems to have a good understanding of who Satoshi is. The CEO of JP Morgan basically says that Satoshi might come back and increase the supply of bitcoin. Basically he doesn’t understand that even if he did come back, he wouldn’t be able to increase the supply.
Only way to do that would be to rewrite the code and have a hard fork which no one would run since it would cause chaos pretty much. This happened in the past with the other bitcoin fork coins but the original is the one with the most work and valid chain.
There are somethings that there are never going to be an answer to it. And one of those things is Satoshi Nakamoto, even if someone comes up today and say I'm Satoshi Nakamoto nobody is going to believe him. Bitcoin is now bigger than whoever created it and it has now become a world wide something which no one can lay a claim to it. The best answer to who is Satoshi Nakamoto will be Bitcoin!! Whenever anyone ask who is Satoshi Nakamoto people should answer Bitcoin.
