I wouldn't be surprised if the US starts funding terrorists via Bitcoin and then blaming Bitcoin. We've had this. The government is stupid. They can't control Bitcoin, they can't take it down. That's their problem. This is something completely new that they have no power on.
I don't think the government will go to such extremes just with the objective of discrediting Bitcoin.
Even if they do fund terrorists, the Bitcoin believers will just shrug it off and life will go on.
