Food for thought.
The food's not so tasty.
But let me remind you that 99.9% of people making predictions are basing their predictions on nothing but wishes and daydreams. There is no math in there.
Let me ask you a few questions, though. Why would the people in the future stop buying BTC if the currency is BTC itself? If the safest, cheapest, fastest, most private way to move money from one continent to another is through BTC, why would the future run out of people buying BTC? If the world is already filled with piles of cash and yet the governments are still continuously printing unlimited money, why would the people suddenly stop wanting to have BTC?
