The NAVX recommended before $SUI has now increased by about 25%, although it can't compare to Deep, which is like the favorite child of Mysten Lab. I feel that $CETUS is seriously underestimated. Additionally, I do not recommend Blue, because Astros under NAVX has already released a test version where you can claim simulated coins for trading, and the official version should not be far off. Just yesterday, they airdropped a few hundred NAVX to wallets for testing. There definitely won't be only Blue dominating the derivatives trading on the SUI chain. However, the trading volume activities on Blue are indeed quite appealing; this week, my trading volume on Blue was only under 50,000 USD, and the SUI given as a reward for the activity is probably worth about 100 USD.
