I think it's simple to answer this question. Bitcoin is an asset that holds value, and like in the beginning, so many people did not even think of investing in Bitcoin, but since the value of Bitcoin has been uncovered, the majority of the world population is all clamoring to have at least one Bitcoin or some fraction of it, and we all know that Bitcoin has a limited supply and not an infinity supply. Therefore, there is still hope that the Bitcoin price will continue to surge in the future and that people will continue to use it. Look at how so many people are now accepting Bitcoin in their businesses as a second option for payment.
On the other hand, gold has a lot of uses. To add up to what someone already said, so many technology companies use Bitcoin for their construction; some motto companies are even using gold to build some motto parts. There are many important uses of gold, but a few to mention.
