Lately, watching on-chain transaction replay has been a bit frustrating again. I just want to quietly exchange some coins, but there's always someone "cutting in line," and the slippage widens, like an invisible person reaching into my pocket and taking a few bucks. To put it plainly, MEV isn't just about a few flashy trades by big players; it's more about people like me who accidentally click too quickly: a few seconds late, paying a bit more, thinking it's just user error.

Recently, there's been talk of some region imposing taxes, tightening or loosening compliance, and expectations for deposits and withdrawals are changing. Everyone's more anxious, the network is more crowded, and the queue jumpers are more ruthless... Emotions stacking up, it's easiest for me to fall back into the old habit of leveraging "to get it back." Remind myself: I mistake simplicity for a trap—when I see buttons like "mindless swap" or "immediate trade" that are too smooth, I pause for three seconds first. Just like that.
