The fiat dollar is not backed by air, but oil. I am not convinced of any of the arguments for a new monetary system to be rolled out after a crash, I think that is hopium. Gold could be added to the SDR, but it does not show up even as a pending decision by the IMF. If I could be convinced that the cryptos will just create a parallel system that will not be outlawed by TPTB I could have more faith in it. But the bankers want it under their control, so how would that be better than what we have now?
