Recently, people keep asking me whether blockchain builders, bundles, and those things are really necessary to understand. Honestly, for retail investors, it's enough to know that "my transaction might be bundled into a bunch, and I don't get to control the order." Don't bother memorizing flowcharts; remember two things: first, don't manually chase prices when liquidity is thin; second, for large or sensitive operations, use protected routing if available, otherwise you might get squeezed, and you'll think you slipped up. As for the so-called "research to the point of being able to fight with builders," I advise you to save your energy— that battlefield isn't for ordinary people to compete in. Recently, the staking/token unlock calendar is being flipped through every day, which is also similar. The anxiety is real, but if you really want to do something, focus on position management, limited permissions, and don’t go all-in at once—just stay alive.
