First, the disclaimer:
Next, the opinion:
Gold has more than quintupled in price over the last ten years, more than doubled over the last two years, and that kind of advancement is, IMO, unsustainable. At some point, people will start putting their money back into securities and other areas that are deemed too risky nowadays, and gold prices will drop dramatically.
I agree with ICOT, with one Caveat (and the same disclaimer).
The only reason why gold has increased is due to perceived risk. Chances are, the risk will go down, and gold may follow. However, as perceived risk goes up, gold may go up as well.
