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.
We all know that there is a lot of differences between bitcoin and also the gold itself. Gold is a physical aspect that we not really easily get while bitcoin it takes time and a lot of effort, hardwork and also knowledge to get plenty of that. We are expecting that the price of bitcoin is more valuable than gold because there are many people given an opportunities to have some money and become wealthy because of this system.
