Litecoin, Cardano, BNB, etc. all have maximum supplies too, but Bitcoin has first mover advantage, as well as the most hash power. Some people argue that makes Bitcoin the most secure cryptocurrency, while others say it has a flawed security model. I may be wrong, but I think it's 1.7 trillion dollar valuation has distracted many people from noticing its flaws.

At the end of the day, cryptocurrencies are like religions and the strongest ones will keep growing, especially during the bull-runs. Those that eat the world will be censorship-resistant, have predictable supply curves, innovate, and above all build resilient communities.

There's still plenty of world for them to eat.
