I think it’s very unlikely that the dollar will be overthrown or that BRICS will succeed in something like that.
Indeed, overthrowing the dollar is very difficult and would have been an impossible task if we were talking about this many years ago. But I think this is no longer true because more and more countries are realizing the abuse of power and aggressive attitude of the United States, and many countries are wanting to get away from the United States. So I even believe that de-dollarization will happen faster than many people think and that it is inevitable, we no longer need to doubt it.
As evidence, the dominance of the USD in global foreign exchange reserves or in international trade has decreased significantly compared to many years ago. Instead, they are increasing their gold accumulation, and that is why the demand for gold has increased sharply in recent years, or they are diversifying their reserve currencies into yuan, euro...It is clear that they are preparing for something, and that is dedollarization.
