Recently, on-chain sandwich/arbitrage is becoming more and more like抢摊位 at a vegetable market: you think you've found a bargain, but you might actually be paying someone else's "queue-jumping fee."

Now I always think carefully before placing an order: whether the slippage and priority fee for this transaction are worth my expected profit, or else I'm just feeding my meat to the knife.

Moreover, recently in some regions, taxes and compliance are tightening and loosening, and as deposit and withdrawal expectations change, the on-chain "urgent to execute" sentiment becomes even more obvious, the more urgent, the easier to get夹.
To put it simply, opportunities are of course there, but more often what you see is someone else's fee bill... I’d rather be a beat slower, at least not just a background board.
