Not so important since gold is a limited resources and has a natural inflation hedge given this.
The real issue is that gold doesn't earn profit. Investing in gold is dead money. It's equivalent to putting money under your mattress, though since it's gold it's a little better. Still, owning productive companies is better (the means of production) because that earns profit which is an inherit hedge against inflation plus addition earnings. Owning a mining company that had gold mines among its many mines would be a much better play than just gold.
