Bitcoin is digital gold that can hit the financial world so many banks don't like it. Bitcoin does have a decentralized nature that cannot be controlled differently from gold which has a real physical and weight, but gold storage must be safe and requires real and feasible space. Bitcoin is sometimes less secure than hackers but has more security if we can store it well and wisely.
Bitcoin is too volatile to be compared with the gold. Gold prices are more stable. I think that if you do not want to risk, you must better invest in precious metals. However, the returns from the crypto may be better.
When we compare this two storage of value , they are both good storage of value , but for gold , yes it is true that gold is a stable storage of value as it grows old ,the value is getting bigger value ,little by little, for bitcoin it is also good for storing value but when the market is hit by this price downfall ,then the value will be changing from time to time.
