Recently, the group has been talking about block builders, bundles, and so on. Honestly, retail investors don't need to force themselves to become researchers... You just need to know: the transactions you send out may not be processed on a "first come, first served" basis; they might be snatched or cut in line by those who bundle transactions, especially for swaps and mints where profits are obvious. Then you'll understand why sometimes, even with minimal slippage, the transaction still feels weird.

I personally think knowing this much is enough: don't publicly reveal too many "readable intentions" on the chain, avoid large batch transactions and reckless slippage, use private routing/protection modes if possible, and don't compete in the same pool at the same second. As for how exactly bundles are assembled or who is collaborating with whom... just get a rough idea; over-tracking can lead to anxiety.

In the past couple of days, before the mainnet chain upgrade/maintenance, everyone was guessing whether projects would migrate. I'm more concerned about whether, regardless of migration, abnormal active addresses and funds are secretly moving—many dark flows are faster than official announcements. The atmosphere in the group is also quite subtle: half are shouting "it's about to take off," and the other half say "don't get too hyped." I'm just playing it safe and observing.
