He's already predicting bitcoin price will go to 1 mil since 2018. I really remembered he was so optimistic with bitcoin price after the big pump in 2017 end. Not just him, people around the world especially who already bought some bitcoins are really optimistic about the rise of the cryptocurrency in 2018. But everything is going down, i'm sure that was a game from whales who tricked people with mass media
McAfee prediction was about $1M to the end of 2020:

And in my opinion his prediction is no different from the one in this thread. Any idiot can think of a price and say it out loud. In the cryptocurrency market, nobody can say that they are wrong, because anything can happen here.
