If one day most of countries in the world ban BTC, will someone with a lot of money spend million or even billion of dollars to establish a whole country. In this country, you will exchange with BTC and other crypto. Will you leave your coutry and move to this 'wonderland'?
to build a state requires sovereignty, unity, land, etc. very difficult to achieve that
suppose it happens, I will not leave my country, because i love my country, culture, and my family.
