Good post. I agree that the banks have so much power over Congress (I'm assuming we are all US) that they will drain the remaining value out of the dollar until the IMF puts us on a North American currency but I think we are only a few years from that if Trump doesn't appoint some folks (to the FED) with gold backing in mind. Read The Creature From Jekyll Island.
When you say government control, you should say bank control. They run the show. They can oust any Rep in DC any time they need to. Also, that control could make BTC illegal in the US. No options to cash out. All it will take a one incident tying BTC to terrorism. They'll probably fake it but they can make it stick.
