Recently, I've seen a bunch of people talking about block builders, bundles, and MEV, acting like you can't trade if you don't understand... Honestly, retail investors don't need to turn themselves into researchers. There are just two things you need to know: first, the transaction order you see isn't necessarily "fair"; someone might bundle, cut in line, or cause your slippage to increase; second, don't always chase market orders with a single click, especially during high volatility—if you can set a limit price, do it; if you can split the order, split it; don't compete with bots on speed.

Modularization and the DA layer are the same—developers are excited as if it's the New Year, while users look confused, which I can understand. I'm now just narrowing my focus: not trying to "understand everything," but only watching for risk points related to my wallet. Long-term execution is actually more stable. As for those proposals that mention "improving user experience"... well, let's see who gets to control the ordering first.
