I have heard also. Rejecting the dollar and buying gold serves two purposes: suppress the dollar as the world's reserve currency AND obtaining real property, as I said. What lends credibility to this is that the Yuan is as worthless - or more so - than the dollar. Owning gold seems to just be 'hedging your bet'.
Russia will accept the Yuan and China will accept the Ruble - both of questionable currency competitive value; it looks to me that the dollar is beginning to slide... certainly against the Euro, the Yen and the Pound Sterling.
The Congresscritters are busy trying to help destroy the dollar with trillions of spending sooner or later ..KaBOOM.
