When it comes to Bitcoin and gold, these two things are really interesting.

In terms of scarcity, gold has been buried on Earth for billions of years, mined little by little, with the total amount fixed and unchangeable. As for Bitcoin? The total supply is locked at 21 million coins, which is hardcoded into the protocol—no matter how much you want to print more, you can't. In this regard, the scarcity logic of both is actually the same.

Getting hold of them is also quite similar. Gold requires miners to carry tools into mines and work hard under the sun and rain; Bitcoin also requires miners to run mining machines 24/7, burning electricity and paying for power. The methods look different, but the core logic is the same: obtaining through cost input.

What's interesting is the global consensus aspect. Gold has been recognized as a hard currency across all races and borders since ancient times. Although Bitcoin has only been around for over a decade, it has already become the only digital currency that can achieve global consensus—this speed of recognition is indeed impressive.

In terms of investment attributes, both are safe-haven tools. Gold preserves value during peacetime and can save lives in chaotic times; this tradition has lasted for thousands of years. Bitcoin, although young, has gone through multiple bull and bear markets and is gradually seen by many as "market chaos insurance," a status that is now quite solid.

What about liquidity? Gold can be exchanged for cash at jewelry stores or exchanges easily; Bitcoin can be bought and sold anytime on any digital trading platform, so liquidity is not an issue.

As for privacy features, gold transactions can be completely discreet; Bitcoin transactions are even more private, recognizing only addresses, not individuals. Both excel in this aspect.

So some people compare Bitcoin to "digital gold," and it's really not just talk.
