Perhaps one day with the current bitcoin advances, bitcoin digital currencies will be an international currency for all countries, and make it easier for every human to make transactions between countries when going to another country.
if it happens in the future it will certainly affect the paper money that exists around the world, whereas we know when the banknotes have a lot of history and symbolize the diversity of a country with other countries.
if that happens, surely the government will not remain silent on the matter, there will be an agreement between state governments to immediately close the bitcoin network to the world.
what will you do if you have a lot of bitcoin.
There are less chances for governments to come united to make it happen as we see cold war between countries. There is a heavy competition in growing each countries wealth and they find roots to grow more. As crypto would certainly benefit the countries in their economy growth and they do realize this, there is a less chances for completely denying bitcoin. What they started doing is, as they found crypto to be strong, they themselves started creating their own crypto coins if you look at.
