Even though there are a lot of other things being built on Ethereum, the only thing that has really kept my interest for many years now is DeFi. There is no bigger use-case than DeFi as it has a total addressable market of the entire planet and can also have the most long-term impact on the world. There is also no other use-case that will drive more value to ETH than DeFi - nothing even comes close in terms of how much ETH demand and value it creates. Going forward, for Ethereum to win and win big, we need to ensure that it remains the home of DeFi (in particular, high value DeFi). We also need to make sure that most/all of the RWA tokenization and TradFi integrations happen within the Ethereum ecosystem. Win DeFi; win everything else.
