What makes precious metals valuable?

The same thing that makes crypto valuable (for now): people assigning it value.

Their use in electronics and other things that the cabal produces?

Gold industrial use is negligible, its primary use by far is as a store of value. It simply has value because people think it does.

Silver, on the other hand, is half store of value, half essential industrial input. You are right that silver's value primarily comes from the latter. If people stopped using it as a store of value, it would still have value because of its industrial uses.

I think the important part comes from the relationship between the two. We've seen that the silver:gold ratio can't be stretched beyond 100:1, prices correct one way or another. It's presently at 90 and recently bounced down hard off of 120ish. Ultimately silver's scarcity and the constant demand for it for industrial uses will drive silver's price up (and the silver:gold ratio down towards its natural 16:1 or so). But if this happens, people who bought silver when it was worth 1/100th of gold will start buying gold now that their silver is worth 1/50th or 1/20th of gold. That'll reveal gold's scarcity, and the price of both will skyrocket.

There is no similar price suppression scheme in crypto, and thus no similar upward potential. The crypto schemes were all aimed at inflating crypto so "they" could pump it and dump it, and a part of the cluster of bubbles they blew has just popped (rest assured, "they" dumped well in advance of that happening).

But decentralized finance is the future. No more middleman. Returning power to the people

That's metals. The ideal form is metal coinage, giving every citizen the choice to bank (and trade in bank tickets in lieu of metal coinage and risk their bank going tits up but gain convenience in exchange) or store your wealth yourself and bear full responsibility for keeping it safe.

Under metallic money, we exist in a state of constant deflation, as natural improvements in efficiencies and technologies lead to ever lower costs for the same product. This rewards savers, who see their socked-away funds buy ever more. Back when things operated in this way, saving was a "nest egg." Cheaper metals are conscripted into currency duty as the more expensive ones become too valuable for day-to-day commerce, and so coinage goes from gold to silver to copper to nickel, and so on.

Under our current system, all benefits of improving efficiencies and technologies accrue to the banks, not to the people who had the foresight and capacity to save. There is no benefit to saving because their money printing artificially devalues money. The only way forward is to borrow, and the only way to borrow is to be a good slave.
