I have seen so many posts about emerging cryptocurrency, and they think that someday it will take over our current system, or it will replace our fiat currency, which is really impossible, yes cryptocurrency is such an excellent currency especially the bitcoin, cryptocurrency keeps on being more prominent and more significant. Still, I think it is not enough to replace the fiat currency. It will be hard for the government to do that.
It will be hard for us if we use our cryptocurrency as our standard currency, the volatile currency will not be useful in real life; only that money is only suitable in real life. Not all individuals are really used in technology, so how could they handle their money if they are not familiar with the technology.
There are still some rural places in this world, so it will be hard for them to adopt the new system if this will be implemented in the future, which I hope won't happen, and even those person in provinces will also get mad if those things happen.
What you talking about, FIAT has already been replaced, it's just a matter of time and architecture of dynamics. LOON are already putting the world on the NET...
Of course, I apologize, but in what places did cryptocurrencies replace fiat? I dont see, there are especially many places where you could pay with cryptocurrencies without converting them into fiat currencies, either directly, using exchangers, or other methods.
