There are two sorts of gold. Physical gold and paper gold. If you have tried to buy real gold coins during the last months you will have noticed that real coins and bars have become rare.
But paper gold is unlimited (certificates, futures and such). Paper gold rises and falls and rises and falls... this affects the official gold price. But it doesn't mean that people actually buy and sell physical gold, only the paper gold is traded.
Imo physical gold is much, much more worth than it is officially traded. A gold price of 10,000 or even 20,000 would be possible if it wasn't for unrealistic paper gold trades.
