Lately I've been looking at terms like blockchain builders and bundles, and in the group, more and more people sound like they're reciting lessons... Basically, retail investors only need to understand that "someone is packaging and ordering transactions," and that's enough; don't push yourself to become an engineer. There are two main points you need to remember: first, the "transaction order" you see isn't necessarily the order in which you clicked the button; sometimes it's just queuing, refreshing, retrying for a long time, and getting snatched away; second, don't blindly believe that "if I place an order, I will definitely get it," especially when sniping hot spots or in low liquidity situations—slippage and being front-run or delayed are quite common. Recently, the debate over staking unlocks and token unlock calendars has been going back and forth, claiming there's selling pressure. My approach remains the same: tiered positions, clearly track the sources of income, and when the chain is very congested, treat it like a library closing—don't force your way in.
