Someone asked me, how much do retail investors like blockchain builders and bundles need to understand? To be honest, you don't have to memorize the entire MEV paper; just remember two points: 1) The transaction you send out may not be included in the block in the order you confirm; someone might "pack" it together with others; 2) As long as there is arbitrage opportunity, your buy and sell orders might be front-run, resulting in increased slippage and worse execution prices. My approach is simple: don't use too loose slippage, avoid rushing in during low liquidity, use private relays/protected transactions when possible, and if you get front-run on-chain, just consider it as paying tuition. Recently, with blockchain games experiencing inflation, studio-driven pump-and-dump, and coin price spirals, it's actually the same—once the mechanism allows for "packable profit," someone will always treat you as exit liquidity... Anyway, never think you're always the smart money.
