Why does no one talk about precious metals when it comes to financial literacy?

I’ve started my journey in financial literacy last year. Still learning and very thankful for the contributors here on Seedly. Along the way, I found out about physical gold and silver commodities and was attracted to its safety and “undervalueness”. I’m surprised how little the number of people talk about PMs. I've now started my journey on stacking metals as a form of savings. You can follow my album on @silver.fortress (ig)
