China, Russia, Brazil, India.... those are big boys. Just so happens those are some of the biggest buyers of precious metals right now too, especially gold.
Here is the deal. Everyone is going to say it will never happen and the USD will be god until the end of time, but in reality, and beyond the reach of the old rich American men who will try to stop it, the fact of the matter is these large emerging nations all can see the demise of the USA in the future. Stevie Wonder can see it coming. They are stupid to not have their ducks in a row when that eventuality happens. The USD is the world currency right now, but it won't be forever. You can count on that.
Face the facts, the USA had a great run. Every great nation before it also had a great run. If history teaches us nothing else, it is that EVERY empire eventually falls. There are no exceptions to the rule. And with the incredible amount of debt the USA has doubled with doomed global fiat currency, there is but one ending to this story and it's not a happy one for Americans. There is no other way to put it.
Good luck with that.
