I don't care about what John McAfee said about some coins project are profitable at the future, he had said with many altcoin kinds but always lower price and drop, never have potential on higher price again.
John McAfee earns his fame, so he needs to be always in the spotlight. So he gains something to always remember and talk about him. Therefore, there will be no sensation in this case. You can indicate any that he is Satoshi Nakamoto. And then what? This person will deny his involvement in Satoshi and, of course, there will be no evidence from McAfee.
