John McAfee likes to do a show. He has achieved success in his life, but that does not mean that he can be an authority in every field of economy or life.
The cryptocurrency market is unpredictable, so his ideas about the price of $100k for Bitcoin in 2020 are taken simply from the crystal ball. I hope this will happen, but in my opinion it is unlikely.
Agreed. John McAfee sure can say whatever he wanted regards bitcoin prices but still no one will know when it will happen. It doesn't mean that if you disrupt the fiat money game you will disrupt crypto currency.
