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?)
The current economic environment is still very poor, and neither side of the trade is very active. The status of the dollar has also been greatly impacted. The dollar is now weaponized by the United States. In comparison, I trust gold more. In the future, there may be exchange standards for multiple currencies, some relying on gold and silver, and some relying on Bitcoin. If another superpower emerges in the future, it is also possible to formulate a fairer world currency and a new economic system.
