Lately I keep seeing words like “block builders” and “bundle,” and my understanding is: don’t think of it as mysticism; it’s more like the “courier sorting” of packing a bunch of transactions into a block. How much should retail investors know? To put it simply, two points: first, the transaction order you see isn’t necessarily the order in which you clicked the button; front-running/sniping isn’t a conspiracy theory; second, don’t blindly trust “placing a slippage makes it safe,” use limit orders when needed, don’t rush in during the hype.

Also, recently hardware wallets have been out of stock, and phishing links are everywhere… I feel that more practical than studying bundles is: don’t click on airdrop links randomly, verify addresses multiple times, and if you don’t understand the signature, don’t sign. The on-chain world is like a puzzle and also like a blind box; focus on the parts you can control first, and the rest… just be aware that it exists.
