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?)
