Well, if BRICS Pay doesn't make use of a Blockchain then it will be as inefficient as its counterpart. BRICS needs to show superiority. And what better way to do this than making use of the latest technologies? A Blockchain-powered payments system would be truly-unstoppable. It would be even better if BRICS used a single currency for transfers that's backed by Bitcoin. The possibilities are endless.
Donald Trump's actions will only fuel "de-dollarization" efforts. I guess it's too late to put a stop to BRICS. Not even higher tariffs will do the trick. We're living in uncertain times, so anything's possible.
