There are many comparisons made between bitcoin and gold.
Another comparison people might want to look into is stone money.

People in some societies carve huge stone coins out of rock to represent their own brand of fiat. The immense quantity of work this process entails is similar to crypto mining processes which can be energy intensive.
The supply of rock coins being limited in terms of production provides a similar function to the number of crypto coins produced being limited by code.
There might definitely be some parallels there.
To be frankly I've never heard of the stone money before, Is it still being used nowadays?
Hmmm In my opinion the gold and other metals are in the physical world and of course its characteristics (e.g malleability ) is the one that gave them the value while bitcoin on the other hand is in the spectrum space and being mined by solving complex mathematical computation. They have similarity but I don't want to label crypto to gold or silver, they are on two different world. The present technology and society need crypto as a currency because of lots of benefits and the technology it holds and gold holds the material value in the physical world that is being admired and used in the industry that bitcoin can't be done but crypto is better when being used as a medium of exchange.
