Lately I've been seeing everyone talk about blockchain builders, bundles, MEV and so on, and my feeling is: retail investors really don't need to push themselves to become researchers… Just knowing that "your transaction might be bundled, front-run, or sandwich attacked," and learning a few tricks to protect yourself is enough. For example, don't rush into pools with low liquidity, don't set slippage too loosely, use private relays/protected transactions when possible, at least don't leave your orders exposed for others to exploit.

There’s so much information that it can really cause anxiety. My filtering method is pretty crude: I only look at two charts—cross-chain net flow and real active addresses (the ones I color-coded myself)—and combine that with a few failed or front-run transaction samples. If I can explain the phenomenon, I stop; I don’t chase after the details of "insider mechanisms."

Also, recently RWA, US bond yields, and on-chain yield products have been thrown into the same pot for comparison. Honestly, what the returns look like is one thing, but the transaction costs and the experience of being drained are another… First, get the execution step clean, don’t expect the returns to make up for all the friction lost in trading. That’s all for now.
