Lately, I've been paying more attention to on-chain activity, and I increasingly feel that the so-called MEV is just about "cutting in line": you think you're placing your transaction in order, but someone ahead of you has inserted a faster transaction, and slippage, execution price, or even whether your transaction can go through at all are all affected. To put it simply, the biggest losers are usually ordinary people who manually confirm transactions and don't want to pay high fees.

These days, I also saw news about some regions tightening and loosening regulations, with tax increases and compliance measures fluctuating, leading to changes in deposit and withdrawal expectations. Everyone is rushing to enter and exit, making the on-chain activity even more crowded, and front-running becomes more obvious... Anyway, I now always wait for one confirmation before placing an order, unless it's urgent. Also, my old habit: when I see strange matching or ordering, I take a screenshot first, and then check back in a few days to see if I was overthinking.
