I also don't understand why bitcoin is always compared to things that are valuable or related to investments which obviously all have differences even though the goals are the same.
gold has existed since the time of our ancestors and has existed since the earth existed and the shape of gold is real and very valuable and will never run out as long as the earth exists, and bitcoin is still 10 years too far with the age of gold and bitcoin is formless but valuable and both are very profitable if you have it.
Cause people think Bitcoin is store of value just like gold that is why they are comparing them. Also, gold isn't unlimited, experts do agree that gold has a limit supply because it takes so much resource to mine and make. It is just the same with Bitcoin which is limited.
It's kind of illogical to compare bitcoin with gold, bitcoin is an asset and should be in the ranks of stocks, real estate, and the likes if anything. While gold is treated as a material of high value due to our ancestors implying it has high values because of it's characteristics both intrinsic and extrinsic. Moreover, bitcoin is heavily engaged with trading whereas gold is affiliated with purchase, which has a great difference
