I suppose he expects people to forget about his prediction by then. I'll be taking down a note and reminding him about his promise after he turns out to be incorrect (which is almost 100% likely).
That said, it might be hard to find a TV station which will want to show John McAfee doing that live based on some crazy prediction he made three years earlier.
When I predicted Bitcoin at $500,000 by the end of 2020, it used a model that predicted $5,000 at the end of 2017.
Oh, well if he has "a model" then he
must be right.
