In terms of reserves, gold requires high costs and security measures to store and safeguard it, but because it is a physical asset, you can lose your savings in a natural disaster or war. This can also be the case with bitcoin, but bitcoin can be very securely stored in cold wallets. Another and most important feature of bitcoin is that it can be transferred and stored anonymously. In repressive and dictatorial countries, people can safely carry and store their savings in the form of Bitcoin in case their savings are confiscated. Bitcoin can be an alternative solution in countries where public order is weak. Bitcoin is not the digital gold of our time and has many options that differentiate it from gold.
Also Gold has more uses as we think in the physical life, I have concluded in that bitcoin is more better than Gold because Gold has less uses in the internet banking etc., While the bitcoin has more uses in the online system.
While we think about the Gold in physical life, it has many uses especially gold mining is increasing day by day and people are using it all over the world very fast. So, comparing these two getting two different levels, each one has its own level in which it is performing. Although If you ask me about who is better I would select the Bitcoin as I love it the most.
