What will be the next DIAMOND, the next SILVER, the next GEM in terms of digital currency value?

They refer to $BTC as digital gold because cryptocurrencies or stablecoins like "usdt" and "usdc" are backed by $BTC. This means that the value of "usdt" and "usdc" would be supported by BTC, a blockchain system that has been in the works and integrating for many years, making it a reserve of value as perfect as gold. Just like the traditional financial system where every paper currency must be backed by a reserve of value (which is gold), a mineral that cannot be replicated, is immutable, scarce, and contributes to technology as an electrical conductor.
If we look at it this way, it sounds familiar to this new digitized financial system where $BTC fulfills certain traits of gold: it's mathematically scarce (only 21 million coins), its blockchain network is so perfect that it cannot be replicated, and it contributes to modern Blockchain technology. It does not depend on any bank or government, making it decentralized, which is why it meets the characteristics of being the value backing for cryptocurrencies and stablecoins.
Now, just as gold exists, so does silver, diamonds, gems, oil, etc. Which cryptocurrencies could become the next diamond or the next gem, the next oil (in terms of value) in this new digital financial system?
