Is the petrodollar doomed? I didn't see anything about digital/crypto currencies in this article--only rubles and linkage of rubles to plain old gold. Now, when Europe buys gas (and possibly oil very soon) from Russia, it appears they will be propping up the price of gold

If other gas/oil producers follow Putin's lead, the days of COMEX paper manipulation of commodity markets will be doomed. Oil/gas consumers may be scurrying to buy physical gold and/or currencies other than dollars, to settle their international accounts.
