USD SWIFT is a dead man walking and any smart country or a sovereign individual should try (IMHO) limit their exposure to it. If BRICS were smart they would adopt BTC as a standard since it is easily verifiable and it is here to stay. It's still very early so they wont do it. Also because the government in these countries know very well they will lose a grip over the financial decisions and they still love their 5 year planning system. Under right leadership US of A will be fine but we will definitely lose the global power status which I don't even think we should be inspired to hold. We are so nicely geographically separated that we can be totally energy independent and stop getting involved in every damn war on this planet. China/Russian connection makes them a solid partner not an enemy. There is no winner in the next war. I hope they realize that.
