Lately, I keep hearing people talk about block builders, bundles, making it seem like retail investors who don't understand will get "completely eaten up"... Honestly, you don't need to memorize the entire MEV process. Just know three things: First, a transaction isn't immediately on the chain after you click; there's someone packing and queuing; second, some people bundle a series of transactions together to抢位置 (抢位置 means "snatch position," i.e.,抢占交易优先权), which may affect your slippage and transaction order; third, what you can do is avoid using too loose slippage, try to use reliable wallets/routes, and if it's a large amount, split the order and go slowly—don't rush in when liquidity is thin.

It's like rush hour taxi-hailing: you send out "I want to go," and the platform (the builder/packer) is carpooling, cutting in line, and dispatching; it doesn't matter if you understand the engine's meaning, what's important is not to stand at the intersection shouting "anyone will do" in the rain, or you'll get scammed.

Also, now I compare RWA, US Treasury yields, and on-chain yield products; I do look at them, but the more "stable" the yield, the more you need to pay attention to the behind-the-scenes bundling/ routing details. Don't trade security for a tiny 0.x% extra just for a little more profit. That's all for now.
