Why do people even discuss such unrealistic and farfetched scenarios? Is it possible? Perhaps it is, although I don't believe it, is it realistic? Certainly not, and if we suppose it's possible, it'll take over a decade or two. There's enough uncertainty in the world already about much more trivial issues than Bitcoin, setting such farfetched goals and expectations that may never become a reality. A lot can change in the global setting that may affect bitcoin and cryptocurrencies, discussing what the price of bitcoin may be in 15 years from now is no use.
