Lately, I've been watching on-chain transactions, and sandwich attacks and arbitrage are starting to heat up again.

You think you've caught a price difference opportunity, click to confirm, but it might just be giving others a "tip fee"...
In plain words, what you see as an opportunity, others see as your slippage and impatience.

My biggest takeaway from being an LP all these years is: don't always think every trade will win.
Sandwich attacks are not something you can educate about; the only things you can control are your order placement method and patience: slow down, batch your orders, don't chase after a green candle.
As for those nested strategies like re-staking, shared security, and yield stacking, I don't want to keep explaining after all the arguing—profits look good, but friction costs and tail risks are very real.

Anyway, I now accept randomness more: I can't control how the market moves, but I can control the fees and position pacing, so that's how I'll start.
