Bitcoin in the media and minds of people has to possibilities:
1. Bitcoin get used for illicit actions, tax evasions and so on. And it harms the consumer, because it is so voltatile and not backed by anything. It could be worth norhing tomorrow.
2. Bitcoin is like the internet. It is disruptive to the current financial system and if not, it was a nice try.
I highly favor #2, at least of America and Europe. They will never ban it! But sure, there will be people who want to ban it. But they will never get a majority.
If #2 is true, it will be a place for free spirits in the beginning and after it is established will be used by the US gestapo to police everyone around the globe.
