I know people out there who have invested a lot in gold under the belief that in the event of like complete societal collapse or hyperinflation, they could use it for purchasing.
I have the hunch it’s a scam, but I haven’t learned enough monetary theory, business, or economics to understand why.
In a societal collapse your best investment is between your ears. If you can build/grow/… things you don’t need to worry about losing value.
