Recently, someone asked me again how much retail investors need to understand about block builders and the bundle set. I feel that knowing "your transaction may not follow the path you point out" and "someone can pack a bunch of transactions into a block" is about enough. If you're not doing MEV, don't force yourself to learn it like a paper; the key points are: don't go all-in on market price during extreme congestion, avoid paying excessively high slippage, and use reliable aggregators when possible. It's best to open a private/anti-front-running option (click if available, ignore if not). I often wait an extra 20 seconds to switch routes to save $0.80, my obsessive-compulsive disorder is incurable... Also, with recent discussions about rate cuts and the dollar index moving together, on-chain congestion is easier to get crowded, and the more crowded it gets, the easier it is to be "used as material for content." Anyway, retail investors should just focus on ensuring transaction quality.
