What many governments don't understand, especially regarding how Bitcoin works, is that it is impossible to ban or eliminate it, since banning Bitcoin is like banning the internet. Politicians who want to control the banking system and force everything to go through it don't realize that individuals can trade Bitcoin with just a device that has internet access and do so anonymously. Not only that, but they can also send funds outside the country to anywhere in the world. Bitcoin has no entry or exit barriers, and governments will have to learn to live with that, and for those who don't like it, too bad.
