If I could only keep one habit: before each on-chain operation, think to myself, "Am I just giving away MEV profit to others?" Honestly, ordering doesn't really "affect everyone"; it mainly traps those ordinary users who are unaware and only click confirm: slippage gets eaten, transaction prices are pushed up, failed fees are still paid, and they think it's just bad luck. There are always people shouting "market efficiency," but what efficiency? Jumping the queue to earn your patience. Recently, the community arguing about privacy coins/mixing compliance boundaries also seems similar: on one hand, claiming to protect freedom, on the other, hiding risks in UX to make newcomers take the blame... Anyway, what bothers me more is not clearly explaining the rules.
