I totally agree with all that. I think government control, and regulation will be the more likely outcome. South Korea has already asked for some sort of international coalition to try and figure things out. I'm sure the G8 and other international government groups will have crypto on the agenda soon as well.

I think the hypothetical scenario that would drive an outright ban would be having it tied into terrorism. We've already seen them try that one in France.

Never underestimate the power of the drug war either. Declaring it an instrument of crime or some other nonsense.

My guess will be that they'll somehow try to ban "privacy" coins, and figure out how to regulate the currencies they can keep track of.
