Recently, I saw people talking about block builders, bundles, and such again. I initially wanted to pretend I understood, but the more I read, the more anxious I felt... For retail investors, honestly, knowing just to "not get caught by others easily" is enough: when you submit a transaction, it doesn't necessarily go directly into the block; it might first queue or be bundled by someone else. If the order changes, your slippage changes, and even the moment you click confirm, someone might snatch your transaction. Anyway, my bottom line now is: don't chase hot topics during congestion, don't set too large a slippage, use private transactions or protection modes if available, and treat outrageous trades as paying tuition and keep a record. As for those builders and how they game the system or who rebates whom... I don't know, forget it, let's not talk about it for now.

By the way, it reminds me of the inflation + studio + coin price spiral in blockchain games: you think the rules are fair, but in reality, whoever is closer to "that bundling layer" makes more money. Retail investors shouldn't expect to outpace those people in speed or information; first, figure out your costs clearly before rushing in.
