I found a pretty good article, I read a lot of them! Of course there's only a few points in here, but it's a good read! It explains how gold ETF funds (banks) have been buying gold faster than ever as of late. They use this gold to let people trade gold at with ludicrous leverages and options.

Whelp, I'm a bit more cynical than your usual bull...
It is these very banks that actually hold (and buying, at high rate) the physical! They set up these more 'lucrative' paper funds, which don't even effect the actual underlying price mechanism (which is buying real physical gold) These paper funds, that are getting a lot of investment lately, swing wildly 10% against only a fraction of a percent of movement in the actual gold price! Of course, any normal person would love to try their luck at this. But there's one very big thing to understand - all the gold stocks, ETF, FX pairs, etc, amount to a larger market than the actual physical gold market! Big money invests into these derivative type funds, and once in position, use their billions USD to move the real physical market one way or another. Since their paper fund holdings have more value and liquidity than they real thing, they gain a lot on derivatives, and lose relatively little by moving the physical market! He who holds the gold makes the rules, so when they are exposed as crooks, they will change the rules! (This won't surprise you, sadly)
It is very dangerous and foolish system, to have more money invested in derivative than the real thing! Alas, that is the world of greed, but take notice, who is buying the real gold. It is governments (some) and banks! Another red-flag? Everyone in the 'know' is buying this stuff, but trying desperately not to send off these red-flags. You won't see this stuff on fox or cnn, and if you do, you know it's almost over, or just beginning, depending on how you want to look at it.
I won't advise you to do one thing or another. I will advise you to research and take advantage of any situation you can though! Gold is money throughout history, it has never failed, but abandoned, for what we have now. What we have have now has failed every single time in history, and there are plenty of examples of it.
