Lately, I keep seeing people talk about block builders, bundles, making it seem like retail traders can't trade without understanding everything... I really don't think it's necessary to push yourself to become a researcher. Just remember one thing: the "public mempool" you see does not equal the actual queue at the moment of final on-chain inclusion; in between, there are people packaging, inserting private transactions, helping you bypass frontrunning, all of which are normal.

All you need to do are two steps: for large or sensitive orders, try to use reliable private channels or aggregators, don't foolishly go naked; for small orders, treat it as a slippage tax, don't be paranoid every day. (Honestly, we're not in the MEV business)
Also, recently some people have been criticizing the lag of on-chain data tools/tag systems, and I somewhat agree. Just look at trends with tags, don’t use them as IDs; path dependency is more like a "habit," not a "real name."
I’d rather wait for an extra confirmation than chase after those seemingly clever real-time conclusions. That’s all for now.
