I think we're going to most likely see a two-system arrangement until eventually everyone moves away from the dollar because it will become obvious to everyone the dollar and the U.S. are not calling the shots anymore. Faith in both is headed south and at some point, that's going to be very clear. We can see it accelerating now with allegiances changing.
When the U.S. began "weaponizing" the dollar and abusing those powers the rest of the world took offense to it. The U.S. made it work since WWII because they were the ONLY real super power, financially and militarily. Not so anymore, especially if we find out China has a lot more gold than is expected they have.
In reality if they move to a system based on a country's commodity wealth that makes more sense to me. The fiat dollar was never equitable anyway. The rest of the world were under our control monetarily and there was not a damn thing they could do about it. We held them hostage with our reserve currency status.
I think we'll see a two tier system come into play until everyone moves to the other side of the boat and anyone holding dollars figures out it's the dinosaur fiat to be holding. That also may be the time we see the Great Reset show up. I don't think we're talking about a long time coming either. Much may depend on what happens in the near term with Taiwan.
