These days, I've been watching on-chain transactions, and the more I look, the more I think the "sandwich" attack is pretty shady: You think you've caught a small arbitrage opportunity, but in the end, you're just being squeezed from both sides, and what looks like an opportunity is actually just someone collecting fees. To put it simply, arbitrage isn't impossible, but you should first treat slippage and transaction fees as costs and record them, otherwise you're just fooling yourself.

The same goes for the blockchain game scene—once inflation kicks in, studios start to fold, and token prices drop, all that's left are on-chain noise and a bunch of "diligent players" paying fees... Anyway, I’d rather go slow now; I prefer not to use market orders if I can avoid it, remember to reclaim approvals, and just stick to this for now.
