I think that the BRICS are quite real and that they will mark a before and after in the entire global geopolitical and economic plane. It is not for nothing that they possess half of the planet's population and a good amount and diversity of valuable resources for humanity.

Are the BRICS seeking to destroy the dollar? I personally do not believe that is what it is about, they are simply creating a parallel and alternative system. To avoid US intervention, and that the US uses the dollar against one of them again, as happened with Russia. And being a little paranoid, I would bet that they use bitcoin to move their payments, after what happened with the SWIFT system. Because something that we can be totally assured of is that none of them will give up the sovereignty they have over their own FIAT currency (turn off the printing press) to adopt some new currency created by all of them or some existing currency of one of the member states.
