"Every Good thing must come to an end" and USD is losing it's trust especially after the Covid because they just started injecting money into the economy more that didn't happen in their history for decades so what they are feeling now is just the after effects of immediate printing money. Gold will be the obvious choice because it's trust and secured or that's what everyone in this world believes and now they also got bitcoin on the line which is a progress that Bitcoin achieved in no time comparing the time period of other assets.
And they were wrong back in the day, so they are finding the right path. I mean since 1971, USD has not been tied to gold, meaning USA had every right to print whenever they feel like it, and they would just print whenever they had debt, pay the debt, and make USD lose value.
Why would anyone trust this currency? Like this isn't a new thing, it has been 50 years even a bit more, since this was the case, so no need to trust it ever. But they did, for some reason, and now the yare realizing, gold is far better, because it is not tied to any nation. In fact, we could in theory say gold is the first decentralized currency, because it has value no matter where you are, and no nation can control it as a centralized figure.
