The DeFi sector is definitely underestimated by the market. Just look at AAVE or Uni, these projects are essential and are truly quality assets. Even Trump's family project WLFI holds AAVE, and they have also increased their holdings in Ethereum and ENA recently.
However, ENA still has 80% of its supply locked, while AAVE has 95% of its tokens unlocked, so the difference is clear.
Now, going back to the data from various chains, Sui has indeed seen an exaggerated rise of over 50%, but its on-chain data TVL has only increased by 26%, which is about the market average.
Sol is just over 100 billion, so Sui is nearing half of Sol's total market value. Whether it is overvalued or not is up for everyone to judge. Chasing high prices now is not wise, as there are many quality coins like Pepe that are still at the bottom and worth considering.
