Well it's nice to see such established public figures saying good things about bitcoin. Obviously i may be biased because i do agree with a lot of things that John McAfee says but sometimes he can be exaggerative.

I think that $50k is a real possibility, the median house price is some countries. Peolpe used to think that bitcoin will never overtake an ounce of gold in terms of price, but it has. Same thing applies to $50k.

But $500k is 10x that, it could happen if USD went worthless overnight but that's probably going to be a very gradual deterioration and not something that will happen in just 3 years. It's a very bold prediction and applaud John for supporting bitcoin but bitcoin isn't all about its price and unfortunately he might have to eat his own dick
