Lately, I've been watching on-chain transactions, and the sandwich + arbitrage vibe is back again.

You think you're picking up a bargain, but often you're just paying others' fees: you click on that swap, and before the price even reaches your eyes, someone has already snatched a piece, then dumps you out...
Honestly, you're not really trading; you're just providing liquidity for others to queue up.

Now I see so-called "risk-free opportunities," I first check the price feed delay and the matching path, especially those where the price suddenly jumps and then quickly returns.
Nine times out of ten, it's not market sentiment; it's either a pool being attacked or the oracle updating slowly, and arbitrage bots love these gaps.
And don't blindly trust "on-chain transparency"—being transparent doesn't mean it's fair; speed and costs are also barriers.

By the way, recently, with social mining and fan tokens—this "attention as mining"—the more I look at it, the more it seems like treating people as traffic pools for sandwiches:
You contribute attention, they take the premium, and the emotional fluctuations left behind have to be digested by you...
Forget it, better to be cautious.
That's all for now, I need to get to work.
