This morning, it was raining and traffic was jammed, and the coffee cooled off while I was waiting... I saw people on the chain talking about builders and bundles again. Honestly, retail investors really don't need to force themselves to become researchers. You only need to understand two points: first, the transactions you send may not go directly into a block; they might be bundled and sent through a "quieter" channel; second, "quieter" doesn't mean safer. When incidents like cross-chain bridge thefts or oracle errors happen, the market's collective "waiting for confirmation" consensus is actually quite reasonable. My approach is very simple: don't chase every detail, focus on whether the final trade matches your expectations, and whether slippage/failure rates are abnormal. When necessary, split orders, reduce positions, or slow down. Over the long run, it's more important than knowing a bunch of terminology.
