This isnt funny at all and it was shocking. But I dont think John Nash was Satoshi Nakamoto at all. Even those evidence are not sufficient enough to back up the claims that he is the real Nakamoto. But in case that he is the real Nakamoto it will never be the end for bitcoins. The community has survived without even knowing Nakamoto and even if he is gone, which is very sad if it is true,  bitcoin will continue to survive.
