democracy promises citizens a government that is of the people, by the people and for the people which means that the people are the key element of what a society that practices a democratic government should be all about.
bitcoin serves same purpose as a currency that is of the people, that is created by a man or group of people that are concerned about the welfare of the people and that is at the same time created to serve the needs of the people and cover for the lapses of the government. a society, individual or government that believes and preaches democracy should natural want to adapt bitcoin since it aligns with her vision.
It ought to be so and even other crypto currencies but it is always a different story for some countries that claim they practice democracy. Their own democracy is just on paper because citizens cannot even express their selves freely and go scot free. Only the government makes the final decisions and it's stands as final without minding wether or not the citizens are okay with it. Bitcoin is a currency that most citizens will love to be used in their countries only in the government will of support to.
