My Dad told the story of being stationed in Korea and being paid in military scrip. It was colored military money. Of course the locals had ways to counterfeit and use it too mainly because their native currency was worthless. It got to the point a change had to be made. So the word came out new blue scrip was going to be used. (I don't remember if it was red to blue or blue to red the idea is the same) The locals were in a panic at the locked gates begging GI's to exchange their red scrip for the new blue scrip. They were offering huge haircuts like offering to give a GI 50 or 75 out of a hundred to change their money. The old was going to soon be worthless and they needed the new scrip to buy things. The catch was a GI could only exchange so much scrip.
The locals needed the scrip for currency as the yuan was so worthless it took huge basketfuls to buy a few simple items. It was so worthless that when transported on trucks if some blew off nobody bothered to pick it up.
The same could happen again here. I'm not an advocate of burying in the back yard. However there is no way they can physically turn every square foot of earth over 100ft deep to find every bit of treasure that determined people have stashed over the last couple hundred years. The way to draw it back into the system is to limit the amounts that can be used in transactions to some ridiculously low number or by going to all plastic money via cards, or by using new different printed money with limits on the amounts of old that can be exchanged for new.
Not only do you need to think about how to protect yourself you need to understand how they will do anything to avoid taking their losses that they have created. No matter what, they aim to steal our money (which is actually our labor) the question is who will step up and stop this.
The framework/laws are already in place to steal everyone's money. My guess is it will happen over a long weekend and come Monday morning ......voila a new paradigm is in place with limited ability to exchange or transact with old dollars.
Those in the past were well aware of what the Aldrich plan (which became the Federal Reserve Act) was designed to do. Everyone screams for continued free money, printing QE and whatever else. Leverage is a nasty function and few realize it works in both directions. They only believe it works in positive ways and that they are getting something for nothing when that is the farthest thing from the truth. The Federal Reserve is a criminal cabal that is only interested in stealing your labor and financially enslaving everyone since they want to be the buyer and lender of last resort and aim to own EVERYTHING.
