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'?
I wonder where would that country be? Who will give or sell a piece of their land to be a country other than theirs? If moon and mars would have been livable maybe could be there.
