When you think of buying gold, you may envision gold bars stacked in a safe just begging for a heist, or imagine the voice of an old-time prospector yelling about “gold in those hills.” When “the world goes to hell in a handbasket,” investors can buy gold in the form of gold coins, gold ETFs and more. In other words, gold offers diversification — a collapse in financial markets doesn’t cause a collapse in gold prices.
