Recently, people keep asking me whether they should learn about blockchain builders, bundles, and how to draw flowcharts. To put it simply, retail investors only need to know three things: your transaction may not be included in the block in the order you think, it might be "packed" and reordered; the slippage and transaction prices you see are sometimes not due to your shaky hands but because someone is better at front-running; during hot market periods, don’t blindly believe you can front-run, especially when the funding rates are extreme—whether the group is arguing about reversals or still pumping the bubble, I just see it as noise. First, clarify your positions and stop-losses. If you want to go a step further, remember to use limit orders, chase fewer trades, and split orders when necessary—don’t treat a single trade as a speed contest against all the experts online. Knowing these is enough to help you pay less tuition.
