Recently, I got the itch again to explain the "block builder, bundle" system. Basically, I'm just worried everyone might use "I didn't click randomly" as an excuse, and then blame luck when they lose money. Retail investors don't need to memorize concepts; just remember two things: First, the transaction you send out isn't necessarily included in the block in the order you see; it might be bundled together and inserted all at once (that's what bundle means), so don't blindly believe "the first one I clicked will be confirmed first"; second, slippage, frontrunning, sandwich attacks—many times it's not that your reaction is slow, but that the channel itself can be front-run by others.

As for on-chain tools and label systems, which have recently been criticized for lagging behind and misleading, I also agree... Labels are not an omniscient view; today it might be called "smart money," but tomorrow it could just be stolen addresses moving. Anyway, my advice has always been straightforward: you don't need to understand enough to build your own tools; just know not to fight against unknown routing, make large batch transactions, avoid reckless signing, and regularly check authorizations—that's enough. To be blunt: don't use complex mechanisms as an excuse; to be soft-hearted: it's okay if you don't understand, but don't pretend to understand and go all-in.
