*flota, you don't, the value is in the $GOLD itself, not the currencies right now that are being used, printed, and manipulated into the price of $GOLD...
Once the fiat folds, $GOLD begins to shine it's real value and gets printed into the money system...
Look at the money that they had when the 'Titanic' sunk, I'd really like to know how much those $GOLD and $ILVER notes would be worth today...
