This is one of the major problems with gold. Despite what some may say, it is probably the most manipulated asset on the planet. Given the fact that so much of the gold is in the hands of sovereign nations and Central Banks that can be pressured by the U.S. empire, this is what happens. In fact, as I have said on many occasions, many of the Central Bank purchases we hear about do not consist of countries actually moving gold to within their borders, but rather just paper purchases. This does nothing to tighten supply/demand for gold. The main countries whose Central Banks actually appear to buy and deliver gold within their borders are China, Russia, Iran, and well, Venezuela. Until that changes, gold will be relatively easily manipulated, which is exactly why I support Bitcoin and why is taking off as it has.
