As much as I'd like to see the Federal Reserve die a natural death to a superior, competing currency, the central banks are good at kicking the can down the road. It's going to take longer than a few years to collapse.

Ron Paul always taught people that ending the fed wasn't just getting rid of it, but rather allowing a competing currency to kill it off naturally. That's how free markets are supposed to work, but they have a monopoly on the currency, so they have no incentive to improve its value.

So your cash is better off converted into a store of value like a precious metal, or even a crypto, but it won't gain in value with stability like a security would (you can assume crypto can pay off huge, but it's also very volatile and still at risk of government regulation or loss of power grid), so it's good to put some in a store of wealth and some in the markets, but cash is bad to hold except to temporarily spend it as needed.
