I don't think there will be a war. Believe me - a war is the last thing we want, anyway.
We want careful, competent, coherent regulation.
What I fear is this could deliver bitcoin into the hands of politicians, opening the door wide open to incompetent regulation, or regulation meant to weaken bitcoin.
Special interests in Washington could easily kneecap bitcoin into being so difficult to use, that it remains fringe. Therefore it would be little threat to the dollar or euro.
