I’ve been toying with the idea of investing in gold directly or having some exposure to it (and silver) in my investment portfolio. I have hesitated, so far, because I don’t really understand why we value gold so much? It just seems so arbitrary. By itself, it really doesn’t do anything. If the world economies to to hell in an hand basket, why on Earth would this metal be worth anything? The answer, according to this article, is interesting because the reason is that gold is uninteresting, at least chemically.
