We cannot compare this 2 together.
Gold - stability, price haven't change for allmost nothing in last few years
Bitcoin - profitabillity, price in higher and higher day by day with small corrections
In my oppinion it is worth to have both.
I do not think that gold is a good option right now since we are living the world full of technology. Therefore, holding bitcoin will give us more chance to earn more money and interact with the future sooner than other people. Although the price of gold is stable, people still prefer something which can bring the more money than usual
Now if you can see the connection between profitability and stability. If something is not growing with time, then what's the use of keeping it? Bitcoins give huge profits and what publics want other than that. Also, you cannot use gold to make fast, large transactions.
