Recently, someone asked me how much retail investors need to understand about block builders, bundles, and these concepts... To put it simply, just understand enough to realize that "you're no longer under the illusion that every trade you make is a fair match." Just remember: the trades you place might be ordered and packaged by others, or even squeezed in between, so don't think you're on the same starting line as institutions.

The "signals" I actually pay attention to are quite basic: with the same slippage settings, does the transaction feel increasingly sluggish after execution, are retries becoming more frequent, even though I didn't chase a high, I keep buying at a tiny peak... These are signs of on-chain squeezing and competition. The approach is also straightforward and rough: use limit slippage sparingly, try to go through aggregators/private routes, and avoid hard pushing during hot periods.

Recently, with some places tightening taxes and compliance, deposit and withdrawal expectations have worsened, and everyone's mindset has become more anxious. The more anxious, the more they chase, and the more they chase, the easier they are to be "packaged and educated." Anyway, now I see TVL dropping, I get a bit cautious—surviving is more important than proving I understand bundles.
