Right now, those "sandwich/arbitrage" opportunities on the chain are more like: you think you've found free money, but in most cases, you're actually paying others' transaction fees... Of course, there are still chances, but the barrier is higher than you imagine. To put it simply, the quick people aren't necessarily you—they're a bunch of bots + closer nodes + those better at calculating gas.

Recently, the funding rates have been extreme, and the group is arguing whether a reversal is coming or if the bubble will keep being squeezed. I'm actually more cautious: at times like this, everyone rushes to trade, slippage gets amplified, and sandwich attacks become even more tempting. My approach is a bit conservative: split large orders as much as possible, avoid small pools, and prefer to earn less rather than turn "opportunities" into someone else's lunch money. Corrections are welcome; I'm still learning.
