It's not going to be used until they realize that bitcoin is what they both want.
Even the fierce enemies are going to trade in some way. They don't trust $ (reasonable) but they don't trust each others currencies even more. They are going back to gold because the trust issues.
The nature of the local currency doesn't matter that much. Even though I'd be more sceptical about CBDC which can be printed even more easily then now.
In this case, if BRICs implements a CBDC, it's not going to matter what it is denominated in, since it's going to just be for clearing payments, as a running ledger. The rest of the nefarious stuff will be implemented later after the transactions at the international level have been proven out.
IMO.
Who's going to run the ledger? You need a trustless ledger. And you're back to either commodity backed currency (where you allow to audit the holdings) or bitcoin 🤷🏻♂️
Not only allow the audit, but also having the trust that you will receive said commodity if it comes to it.
It is much better for them when the value is stored within.
Better in general, but not so much for ledgers of physical goods being traded.
I don't expect and large states to run a trust less ledger that would give up a vector of control, and I don't see that as a desired feature of the system from their perspective.
