Your best investment would be a book on economics or somebody who actually knows something about the subject...and I don't mean the right wing morons that frequent this site.
Gold (and silver) is an INFLATION hedge. It goes up with expectations of inflation. In a real economic collapse, you will lose your shirt. Consider that in the Republican disaster in the second half of 2008, the price of gold FELL 30%. That's when everybody was convinced we were headed for a second Great Depression when Obama was elected. ONLY after the depression risk was contained did gold and other commodities start to go up again.
Buying gold now is essentially a bet on large scale stimulus in Europe, and that they will avoid a depression.
Yes, I still have gold futures--but I bought them initially in early 2009.
