Gold is predicted to hold more buying power than cash over a 10-year period due to inflation, although this is not a certainty.
"My theory is that if I buried $10,000 worth of cash and $10,000 worth of physical gold in my backyard, my theory is that in 10 years the gold would have more buying power than the cash because of inflation. Am I certain? Absolutely not. But that's why I own a little bit of gold."
