A slower pace is actually quite suitable for retail investors, especially when discussing blockchain builders and bundles and that kind of stuff. You don't need to become an MEV engineer; just having a rough idea is enough: after you click "Trade," it doesn't go directly on-chain and execute immediately. In the meantime, it might be seen by the packagers, snatched away, or inserted into someone else's bundle of transactions. Basically, it's like shouting your price in the open market while someone nearby is wearing night-vision goggles.

My own "sufficient understanding" boils down to three points: First, don't chase meme or celebrity tokens that suddenly become popular across the entire network; attention shifts quickly, and the last one often ends up being retail investors. Second, don't set slippage too high, and use private routing/protection modes when available—at least don't expose yourself too openly. Third, when the network is congested, don't be a millisecond chaser; even if you get in, it doesn't necessarily mean you'll profit. Anyway, I'd rather eat a smaller slice than see the same disaster during audits or post-mortems again.
