It's wrong to compare bitcoin in gold because people using both in different cases. Gold is better for saving money , bitcoin is better for multiplying owners goods.
I think it is normal for them to compare these assets since a lot of people are trying to find new ways to invest their money at that will give them good results and since Bitcoin is a new hype, a lot of people want to risk their money their but Gold is also a good investment. A lot of good and intellectual investors say that metals are good investment, that also includes gold.
