So there are no attractive world reserve currencies to compete with the dollar. History has shown that whenever a) currencies are not desired and b) there are no other currencies that are attractive to go into, the currencies are still devalued and the capital finds its way into other investments (e.g., gold, commodities, stocks, property, etc.). As a result, there is no need to have a strong alternative currency for a devaluation of a currency to take place.
