I'm not very good at... spotting "sandwich/arbitrage opportunities," I’m better at watching for that moment before you confirm: you think you're picking up a bargain, but in reality, you might be giving others a fee. That fleeting "cheap transaction" on the blockchain often isn't the market rewarding you; it's someone seeing your order in advance, trapping you in the middle to squeeze out some profit... To put it simply, what you see as an opportunity, others see as your slippage.

Now I see a long string of routes, and pop-ups that let you approve unlimited limits, and I get annoyed: don’t rush in first, first revoke permissions, don’t set slippage too high, better to have fewer transactions than to act as a free ATM. By the way, the recent NFT royalty disputes are also quite annoying; creators want to earn more, which is fine, but if liquidity in the secondary market gets too restricted, it might end up being "traders pay more, faster runners earn more," and we’re back to the start... Anyway, I plan to revoke permissions weekly to feel more at ease.
