bitcoin is not specifically for a particular country but bitcoin is made for people who are interested in investing in it, so in my opinion bitcoin will not fall because it is not controlled by the state but by enthusiasts, so in my opinion bitcoin for the future certain be bright.
not just investing but in using this also, we cannot deny that in the past years bitcoin become popular because of people using this for their payments online and even in gambling online.
so i think this is not only for Powerful nation or not even in lowest nations instead this is for the world to use and to progress.
