How much do retail investors really need to understand about blockchain builders and bundling? I think you shouldn't push yourself to become a researcher... Knowing three things is enough: the moment you click "swap/buy or sell," it might not go on-chain immediately; it could be bundled into a bunch and sent to the builder; this can reduce the chance of being front-run, but also means you trust that path more; and finally, don't believe blindly that "setting a slippage makes it safe," because slippage is just your maximum tolerable loss, not a protection against front-running.

As for how to do it, honestly: use a wallet/router you trust, don't install shady "gas-saving" plugins; for large amounts, split them up, and don't chase confirmations when you're emotional. Recently, social mining and fan tokens—this "attention as mining" concept—sounds like a new narrative, but it's actually like bundling: wrapping risks you don't want to understand, so you only see the "sense of participation." Anyway, I’m not really into that stuff.
