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.
But, at stake is the irony that the FinCen analysis points out. Any attempt to regulate these special (over the counter) OCD "swap" derivatives would kneecap the Fed and all the TBTF bank monopolies abilities to fix market and bond prices by insider trading "off their books" all day long, every day and twice on holidays.
If they even open the door a quarter inch to the CFTC to regulate OCD Swaps they will have the full vengeance of the financial industry gunning them down.
https://en.wikipedia.org/wiki/Commodity_Futures_Trading_Commission#Over-the-counter_derivativesThe problem with Bitcoin is the idiotic market trading exchange nonsense, which might create an opening for them to allow the CFTC to regulate this one form of a swap precisely because it is publicly "traded" in a stupid market.
