PKv, you actually nailed it why I tend to not listen to Travis.
Good on you for your bank actions.
In my opinion, if things crash your credit card will be worthless quickly. Then the banks will close as per the Treasury so cash will be king. Then, within weeks after the crash, cash will be worthless and things will change to PM, and bartering.
We have a list of things we will buy the second the crash happens using cash on hand. Hopefully, before cash becomes useless. This is when PM's could save your butt.
Just look at what happened to the Weimar Republic. It is the text book of what is coming.
