I am a bit disappointed that the article later says:
Historically, new world reserve currencies are backed by gold.
Prices just dropped on gold and silver. NOW it the time to buy! Protect your wealth my friends.
As if gold and silver will be the next world reserve currencies.
The optimistic me says that Bitcoin will be the next world reserve currency after the dollar, but that is depending on countries using it, which's already starting to happen in some countries. Sadly the article dod not say which fiat currency is the most viable alcandidate to replace the dollar (the yuan?)
Looks like the writer of the article is a heavy precious metal shill

Imagine going backwards just because you don't want the current reserve currency almost everyone uses. But anyway, if these countries indeed abandoned the USD, chances are they will be making moves to promote their own currencies and make everything centered around it. The question is, would the rest of the world be ballsy enough to follow their lead and abandon something that they are using to peg literally everything with in the world market? Chances are, no, the world is not ready to do that. The listed countries only abandon the USD because the said currency is weakening their own. But if they are to trade in the world market, they'd still need to transact in USD because not everyone follows what they are doing.
