I would rather speak about both Bitcoin and Gold as I believe both should be a part of your portfolio for better balance. Diversification is the key of a healthy portfolio. So I always consider keeping gold in my portfolio for capital protection. Bitcoin is a very volatile assets and it is highly risky. So adding gold in your portfolio gives it a nice balance of capital protection because gold is not volatile. I always prefer paper gold to avoid making charges.

So instead of comparing gold with Bitcoin, adopt both of them. Both assets are valued based on rarity. Bitcoin has a fixed number and gold supply is also slowly depleting. If you are really serious about your investment, you must not ignore gold and should also include Silver in your portfolio of investment.
