Lately, browsing mempool feels a lot like watching people fight: on one side is "Wow, arbitrage opportunity," and on the other is "Oh, it turns out I am just paying fees." As for sandwich attacks, honestly, you think you're trading with the pool, but you're actually competing against a group of people watching you to see who can be faster and more ruthless.

My current, rather simple way to avoid impulsive trades is: when I see that tempting move, I first close the trading window, check the transaction history and slippage on the chain for two minutes with the same pool, and casually raise the gas to a "normal person" level. Then I ask myself: if this gets sandwiched, am I still willing to accept it? If not, don’t click confirm. Anyway, many "opportunities" end up like inflation spirals in blockchain games—looking lively, but in reality, you're just moving bricks for studios or bots. For now, that’s how I do it; taking it slow isn’t a big deal.
