Recently, the group has been talking about block builders, bundles, and these topics, and it seems overwhelming for newcomers. To put it simply, retail investors only need to know three things: 1) The transactions you send may not be added to the blockchain in the order you expect; they might be "bundled" together and processed; 2) Don't blindly trust your quick fingers when snatching attention-grabbing things like Memes—often, the last move isn't about speed but information advantage; 3) If you're placing large orders or are sensitive to slippage, try to use reputable wallets with private sending options or anti-front-running features, and avoid running naked in public pools. The more underlying mechanisms you understand... it's okay, but don't let yourself become more reckless the more you learn, because the risks are the same. The group is quite divided now—some people chase trending topics every day, while others just want to quietly calculate real annualized returns. I belong to the latter.
