I know it's a bit ridiculous to say, but you can always pay cash. That's how Wagner works.

I think a gold-backed currency is the best approach, but it makes no sense to be only backed by gold by 10%. It just means it will lose 90% of its value on the first trading day.

So, what do the BRICS produce exactly? Energy. While it's interesting for BRICS to *sell* their BRIC coins, it's not interesting for them to receive (aka get paid in) because they still need access to the EU/US market, which is unlikely to accept the BRICS coin as payment because you cannot buy much with it.

Do you seriously think a BRIC country would contractually lock themselves (they won't) with...the IMF? An institution also directed by the West?

Once again, the main problem here is trust.

No one trust either their political system, nor the state of their economy.
