As far as I know, not only John Mcafee predicts the price of Bitcoin to reach the level of $ 100K, many politicians or those who predict the price of Bitcoin can reach the $ 100K level, there are other entrepreneurs who predict more than that.

My understanding of Bitcoin speculation, of course everyone has no prohibition to make speculation for themselves, logic if John Mcafee remains optimistic or confident in himself about the economic situation, Bitcoin or the development of technology at this time, I am sure he did not "commit suicide by hanging himself" precisely many people were not sure what he said again, This means that John Mcafee no longer believes in himself so he acts carelessly and silly for himself, what people expect like that, does not exist.
