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.
