These days, I've seen a bunch of people scare others with "staking unlock/token unlock calendar" to create selling pressure, making it seem like all sell orders can precisely hit your head... Actually, for retail investors, you don't need to study the block builders and bundle sets to the point of writing code. To put it simply, you just need to know: many transactions are packed together into blocks, and the order is not "first come, first served," so don't be superstitious about rushing ahead. Anyway, I have only two approaches: don't aggressively market buy when liquidity is thin, and when you see the same large order repeatedly "cutting in line" on-chain, treat it as noise—don't get caught up. Understanding that "transactions may be reordered, slippage occurs, and trades may not execute as you expect" is basically enough.
