It depends, probably in a small country if everyone start using a crypto currency and left over creditcards, they economy may collApase.
You don't get a point. How the majority of the people left over the credit card makes the economic collapse. The crypto disturbs the countries economic through the majority of the users are using it as investment place. That makes the majority of the countries will lose a lot of money because it was flying to another place. Just like what already did in some countries to ban the bitcoin. majority of them are mentioned if the crypto was disturbing they're economic. To prevent the potential investors move to another ground.
So far so good that Japan has been regulating cryptocurrency activities and so many other countries as well; I really do not see how their economy is crumbling. I feel we are taking this too much to the extreme. The bad sides we are looking at are not really even there in the first place and for people having lot of opportunities to even earn and make some extra bucks, that is more like even pulling funds into the system.
Crypto may change the way we do things, but I do not see how it would affect the economy as a whole. Fiat system on its own is already weak, and if by getting the fiat crumbled, I really do not care.
