Recently, I keep seeing newcomers ask if block builders and bundles are "insider tools." Actually, retail investors just need to know how to avoid pitfalls, right? To put it simply, just remember: the transactions you send on the chain are not necessarily packaged in the order you confirm them. Someone might bundle a series of transactions to grab priority (grab priority means "grab priority"), so slippage, failure fees, and being inexplicably front-run are not some kind of mysticism.

In my own spreadsheets, I don't write too deep into the structure... just leave two columns: how is the experience of being front-run on this chain/DEX, and whether I use private routing/protection mode. Don't think about researching enough to compete with the builders—that's a different professional track.

Especially now, with memes and celebrities calling signals one after another, when attention shifts, it's easiest to turn into "I just want to try it out" and then end up taking the last baton. If you're really going for it, at least don't set too loose a slippage, don't chase the candle tips, since the transaction fees are real.
