#Bitcoin is not a captured market and diamonds are a scam.

Yes you or your wife can desire whatever you want including diamonds, like many others you can pay a lot for diamonds and think whatever you want about marketing campaigns. Lots of people spend lots of money on things other people don't value. Yes value is subjective.

Everyone is free to think what they want but not everyone is free from the consequences of those thoughts and decisions.

In a war zone bitcoin is objectively more useful than diamonds because it is easier to move and harder to steel. But some people still might choose to hold diamonds in a war zone instead of bitcoin. Who has a better chance storing their value successfully, the person holding diamonds or the person holding bitcoin?

There are other similar, critical reasons why educated people on diamonds and bitcoin would choose bitcoin as an asset, as property, as a medium of exchange and as a store of value.

One critical reason is scarcity, like with gold most people cannot tell the difference between counterfeit and real diamonds, they rely on what experts tell them. If you trade diamonds for something without an expert available, say you need something in exchange for your diamonds, how can that person know the value of those diamonds and if they are real?

Diamonds are only becoming easier to counterfeit and can be indistinguishable from manufactured diamonds. Gold is counterfeiting is also advancing with technology. Scarcity is critical.

Also diamond markets, technology and areas to mine diamonds are captured. Inhuman mining practices like forced labor are utilized.

And yet there is no known capacity for diamonds, they are common within the earth. It's fictitious scarcity at best and a crime, an objective monopolized crime syndicate. It's a crime because of the slave labor, the monopolized market and captured mining. Scarcity is critical.

And scarcity is a big reason why bitcoin is better than gold, diamonds or your favorite land etc. Yes if you are in the desert with no water source water becomes more important like Saif said.

Water is incredibly abundant and drinkable water depends and your knowledge and ability. Your ability to distill or otherwise purify water. Your ability and know how to find clean water and or knowledge of clean water sources. You can make more water drinkable. You cannot make more bitcoin.
