Even if they do manage to create a trading block between countries, launch a settlement reserve currency to store excess income in, instead of dumping into the various local currency bond and stock markets, and help balance of payments, it's not going to do much for the average citizens spending power, they are still stuck with local currency which has already established a trajectory of inflation and thats not going to change, yes this BRICS reserve currency can help in certain ways to reduce debasement pace but not the trend
This is just a federated fiat shitcoin
So no, for me it changes nothing, stacking harder than ever
