I used to be scared by words like "block builders," "bundles," and "MEV," feeling that if I didn't understand, I would get cut; now I think, retail investors just need to understand "don't consider yourself a system player." To put it simply: the transaction you send may not be included in the block in the order you want, someone might bundle, jump the queue, or cut in front of you, especially when you're in small pools, setting too large slippage, or chasing gains and cutting losses—that's most obvious.

My current approach is pretty simple: I'd rather earn a little less, set slippage to a fixed limit, and try to use places with good liquidity. Don't leverage wildly when the market heats up. The narrative about ETF capital flows has recently been linked again to risk appetite in the US stock market. When sentiment rises, these "packagers" on-chain will only be busier... Anyway, I focus on controlling what I can, and don't blame all losses on being "cut." Stop-loss is more effective than overthinking the terminology.
