For me I choose gold all the way you will never lose in gold 
But now i prefer to choice Bitcoin. Cz bitcoin is decentralization crypto currency, it will never be stable. Many people interested to invest in bitcoin increase day by day.Previous some years many people benefited by hold crypto currency like BTC.But both are most valuable in their own goal.Since 2012-13 bitcoin price was too low but now bitcoin price average $19k+ you also know it it already touched in $66k+ in 2021.
Can say both are good, if you have a lot of money and don't like risk then gold is a good choice. But if you only have a small amount of capital and want to invest in something that can yield big returns, then bitcoin is a better choice than gold. Gold is not highly profitable but safe and low volatility, bitcoin offers high return but high risk because of its volatility. It depends on the investment needs of each person.
