Anyone can make their own prediction but we can't say either if their predictions are right or wrong so we can't take it seriously. Mcafee said that Bitcoin will reach a million dollar by 2020 this means he believe that it will happen this next 2 years, I also believe that Bitcoin can reach this level but I doubt that it will happen this next few years because the market will cannot always consistent bullish and whenever we see a huge price increase there is always an expected fall back. When Mcafee started this coin of the day/week/month I just started to hate him because it makes no difference with a pump and dump scheme.
