I keep running into newcomers who, while chasing memes, ask, “How much do you really need to understand about block builders and bundling?” To put it plainly: for retail users, knowing enough to protect yourself is enough. You should understand that the swap you click isn’t recorded on-chain immediately—there can be bundling in the middle, you can get front-run, and even you yourself are effectively competing with bots for the right to be processed first… Don’t think about researching hard enough to catch MEV—that’s just too much effort.

My habit now is: for large amounts, split it into several transactions and set very conservative slippage, or just use a protected order placement method; for small amounts, go with the flow—don’t sacrifice yourself just to save a few bucks in fees and end up being the last one in the race. A couple of days ago, I really got tricked once by that “save on fees” mindset—turns out the execution quality was absolutely terrible, and I ended up laughing in sheer frustration.

And there’s a small change too: I used to watch the charts and feel itchy to chase the move, but now I set reminders/limits for myself. I don’t act before the trigger—after it triggers, I check the estimated execution first… and my mood is actually steadier. If I miss out, I miss out; at least I’m not sending money to someone else on the chain.
