Anybody's guess.  It is so manipulated.  US mint sold out of gold last month.  Hmmmm. Price goes down, they sell more gold.  Hmmmm. 

Paper gold trading is how they drive it down.  They don't want people putting their money there.  They want them to either invest or spend, not save. 

Which cup is the pea under?   Just a shell game.
