Cryptocurrencies including Bitcoin are the future whether someone like it or not. Sooner or later they will become equal to fiat money. New technologies are taking place of old ones and so it's in the world of finances. The development of cryptocurrencies can't be stoped anymore.
The development of cryptocurencies has never been a question as to whether or not it could be stopped, but how much it would catch on. No-one can stop anyone from changing or developing anything. We have to still see if it will continue to grow, but so far it is showing strong signs of continuing in its life span and cryptos probably aren't going anywhere.
That is what matter, how bitcoin could catch on/ equal to fiat money or more than it. where you can spend it at anytime, anywhere you want as an International accepted currency (need more than 15 years imo)
I have to disagree if cryptocurrency aren't going anywhere, where you have been all this 7 years of bitcoin rises?
I thought we know that bitcoin are going from nothing to $800 in value, many merchants and big companies accepted bitcoin payment even these are not enough for now. With all of those progress, bitcoin already reach the highest value of currency, what if more business, merchants start to join in bitcoin world? That's how bitcoin could catch on.
