Metal has had value since the beginning as tools, weapons, and as money.
For the last 8,9,10 years I hoarded old pennies and nickles knowing full well the eventual effects of Inflation, see Coinflation. You see that even an old penny commodity value is worth more than it's face value.
Fiat currency is but a mere representation, a promise of value, a promise subject to human rationalization and abused out of power and greed. With crypto I prepare for the world's biggest rug pull scam organized by the powers-that-be.
