go check again how states work.
The BRICS will choose a system that isn't in danger of having to have a fight with any US regulator, that can't get its documents subpoenad by any US agency, that can't be made to give access or hand over data, that can't have their offices raided by US stormtroopers and that aren't otherwise dependent on US structures. That is a 0% chance for ripple, then.
I will take a bet on that. But not in ripple.
