Lately, everyone has been talking about block builders and bundles, and the more they talk, the more it sounds like they're reciting lessons... To put it simply, retail investors just need to know how to "avoid pitfalls": the transaction you send isn't directly added to the block; someone might bundle, cut in line, or reorder, resulting in larger slippage, confirming but still getting front-run, and sometimes inexplicably failing. Don't worry about who uses what private channels first; focus on doing the default operations well: avoid blindly market orders during high volatility, leave some slippage buffer for yourself, and use wallets/routes with anti-front-running features if possible—don't be greedy for that tiny edge.

And now, with the heated debates over privacy coins and mixing compliance boundaries, I have just one feeling: the more "invisible" something is, the easier it is to think you're safe, but in reality, it's just greater information asymmetry... In the end, it all comes down to waiting: waiting for confirmation, waiting for a pullback, waiting until you're clear-minded before clicking that button, or you'll easily be driven by emotions.
