Recently looking at on-chain transactions, sandwich attacks and arbitrage, to be honest, you might think they are opportunities, but often they are just paying others' transaction fees. Especially when slippage is large and pools are thin, your "bottom fishing" might just be helping MEV bots earn a meal.

Now I don’t look at opportunities for excitement, I focus on three things: how far the collateralization ratio is from the liquidation line, whether the lending spread suddenly widens, and whether the trades are a bunch of orders at the same price (which is when you’re most likely to get sandwiched). It’s normal for NFT royalties to be a heated topic; when secondary market liquidity is poor, everyone wants to pass the friction costs onto others, but ultimately, traders pay the bill.

There are many tutorials, but I prefer those that break down failure cases, slippage/fees, rather than the passionate “seize the opportunity” type… Anyway, I’m cautious, living first.
