Lately, I've been watching on-chain transactions, and sandwiches + arbitrage are everywhere... You think you've scored a bargain, but often you're just helping others pay a "fee hotpot." To put it simply, when slippage is large and gas is hurriedly withdrawn, entering the market is like rushing through a congested intersection, only to find that your car hasn't gone much faster, and you've paid double the toll.

I'm now basically: prefer to be slow, place a limit order (if I can), rather than chase pools that suddenly surge in volume. Especially recently, with some regions tightening taxes and compliance fluctuating between strict and relaxed, deposit and withdrawal expectations are wave after wave, making people more impatient, and impatience makes it easier to get squeezed... Anyway, I no longer believe that "being fast enough can win," most of the time, the winners are miners and bots. For now, saving a bit of gas is enough to make today’s watch worthwhile.
