Gold is a very particular asset
Gold is not a company, pays no income and promises nothing. That is exactly what makes it different: it exists as a real, recognized and exchangeable asset.
Its value does not come from a coupon, a dividend or a future promise. It mainly comes from scarcity, global liquidity and the trust it has kept over time.
In calm periods, gold can look useless. But when purchasing power becomes harder to preserve, it can again become an easy reserve sleeve to understand.
