Recently, I've seen people on the chain chasing "sandwich + arbitrage," claiming it's an opportunity.

Honestly, the small slippage you see might just be someone else's daily bread.
Especially those who jump in with a market order; when the order book jitters, they get squeezed from both sides, and retail traders think they're just unlucky...
I'm more focused on monitoring exit paths and liquidity, rather than whether I can "squeeze out" a profit.
Lately, everyone has been complaining about validator/miner income, MEV, and whether the ordering is fair—I don't have much to add.
Anyway, think clearly before trading: are you here to make money, or just to collect fees for others?
If you really want to play, at least use limit orders, split your trades, and don't go head-to-head in pools with low liquidity—start with that.
