Gold is still a very popular choice for people but if you look at the returns then there are relatively negligible returns over gold investment over past few years while bitcoin has shown huge growth in just 13 years so for me bitcoin is the best option to invest your money in.The main point is you can use it and convert it to fiat or directly spend it if possible but that's not the case with gold and moreover government control it but bitcoin is your asset not anyone's else.
Here is quote from Satoshi himself while making this prolonged comparison:
It's the same situation as gold and gold mining. The marginal cost of gold mining tends to stay near the price of gold. Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange.
I think the case will be the same for Bitcoin. The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste.
The gold supply is at the time not known and with mining it comes to existence and not a good investment for me so bitcoin is good option according to me.
