McAffee won't eat his dick and that's because he'll probably be dead before then. Otherwise it's chow time. $1m just seems like a lifetime away from where we are now, even if the site you linked may suggest we are only slightly below where we'd need to be in terms of growth since his prediction.
I don't think that should even be taken seriously. The old man probably just aims to get more people into investing by making such radical assurances. Well i'm hoping he's right but at this rate, we're nowhere going to be close to that target in 2 years
Actually as the link shows at this rate of growth we're not that far below where we should be, but that assumes a static rate of growth which is unrealistic.
But in any case 1 mill for a coin is pretty much impossible by modern dollar values, if it lost 90% of its value then possibly that would justify it.
It's the only scenario in which it could happen, the dollar would have to go through hyper inflation, that might happen but not within the next 2 years.
