I support dedollarization, but honestly, I have never thought about what currency will replace USD, and I do not expect that to happen either.
What difference would it make if another superpower replaced US, but the world remained unipolar, with power concentrated in a single entity? Instead, why not look at the bigger picture? The world does not alway have to operate under a model dominated by a single superpower. The world would be a much better place if it were more multipolar and power were distributed more evenly instead of being concentrated in a single entity.
But tell me honestly—what don't you like about the dollar as a reserve, “unified” currency for international settlements?
I'll be honest—my only complaint is that I'm positively jealous that they managed to pull off such a feat and that the dollar has secured this position

I can't find any other objective reasons for disliking the dollar, on which virtually the entire model of mutual settlements in the world is based...
As I said, I believe the world would be better and more prosperous if it were more multipolar instead of unipolar as it is today. Even if it were not USD, but yuan or euro, I would still object, and what I object to is the monopoly and abuse of power.
I support dedollarization not because I utterly hate America or the dollar is problematic, but because I hate a unipolar world
I do not understand why everyone says they hate dictatorships and monopolies, but then supports a unipolar world where power is concentrated in the hands of only one power. That is really contradictory.
The dollar as a reserve currency is not about “bad USA”, it's about the unification of the payment system. A single mechanism on a single currency is CONVENIENT! Just imagine the international economy without a single currency, but with 250 currencies from different countries. From the point of view of even the technical implementation of the international settlement system, this is a very complex system. And imagine, for example, what a grocery store would look like where:
- potatoes come from Egypt
- sunflower oil comes from Ukraine
- strawberries come from Israel
- mangoes come from Thailand
- beef comes from Brazil
- rum comes from the Dominican Republic
- spaghetti comes from Italy
- ...
etc.
How would the owner of the store/chain purchase all of this in different currencies, keep records, and account for the risks of the currencies themselves?
And most importantly, the US does not force you to use the dollar—trade calmly in your local currency, there is no such ban and there cannot be. The question is whether your economic partners will agree to this...
