Gold and silver ***IS MONEY***. Always has been, probably always will. There's 5000 years of history in that statement.
EVERYTHING else are derivatives of money. As derivatives, each thing that purports to also be money, which is merely derivatives of money, introduces to some extent, more or less, third party risks.
The dollar currency today, is a derivative of money. It has a third party (the FED, central banking) risk. And, in fact, it's value today is nearly worthless, compared to the 1913 dollar, to the tune of 3% of what it was back then. So, we can reliably presume that this erosion would just continue, should the fiat dollar, a derivative of money, continue from today.
I see the fiat price of silver, rising to $79, as a sign that the dollar is falling further below that 3%.
Currencies don't last forever, and we're all witnessing a remarkable event - the end of the fiat dollar, and should expect that there will be something to replace it. If replaced by another fiat, the cycle would repeat because bankers (aka banksters) will be banksters.
But, I expect the next currency to be PM-backed. It's the Trump 'Golden Era' - so much that happens around the Trump admin is golden - the Oval color, the talk about Powell and FOMC members, on the IRS, Tariffs.
