That will be happened to most of the countries. Due to the financial crisis in Venezuela, almost 60% of their population is now heavily interested in cryptocurrency. And the same will happen in some country too. I'm expecting a huge crisis world wide before the mass adoption of the cryptocurrency.
It is true that all the possibilities of the threat of a financial crisis that will occur in some of the world can occur if the finance department of various countries does not have a good arrangement, I think it will happen, just need to wait for the time when that happens.
