I would like to take up the points of an article published on
Bitcoinist. (Even if some will say that this media is Pro-Bitcoin the points are the most important.)
1. Laws Cant Be Written Against Bits and Bites
2. You Cant Ban Open-Source Distributed Software
3. Bitcoin Can Be Broadcasted via Satellite
4. You can Send Bitcoin Via SMS
5. You Cant Shut Down the Power Grid
For me, yes bitcoin cant be banned even theirs countries already ban bitcoin, it's just like prohibiting their people from using bitcoin because in another side this ppl can still use bitcoin but illegally in their country. People can always disobey the laws whenever they want it, but if you caught, the consequence is also priceable. They truly cant stop that list.
