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.
Some (many? most? IDK) gold sellers are scammers. They will sell you overvalued stuff and insist it’s extra-valuable because of some feature they made up. They are the ones being loud on the web and making you hear about it all the time. So, if you hear an ad, and buy gold, you’ve probably fallen for a scam.
But investing in gold by itself is just like any other commodity. And just to say, the rule on that last phrase is valid for almost everything (it’s absolutely valid for stocks and investment funds).
