Recently browsing on-chain records, I saw someone doing sandwich + arbitrage operations, which on the surface seem like easy money, but in reality, what you see as "opportunities" are often just the transaction fee entries calculated for you by others... To put it simply, when you click swap, a bunch of bots are already lining up behind and in front of you, and if you set a larger slippage, it’s like having food delivered straight to your door.

I generally don’t chase those small profit margins that look like guaranteed gains anymore; I’d rather earn a little less than become a charity for liquidity and gas fees. The same goes for cross-chain bridges—when it’s busy, I’m most cautious. First, check the audits, then monitor the activity. For large amounts, split the transactions into several smaller ones to proceed slowly, so I feel more at ease.

By the way, about that recent social mining and fan token “attention mining” concept—I feel it’s quite similar to the sandwich logic: you think you’re mining, but maybe you’re just paying attention as the transaction fee... Anyway, I’ll keep observing for now. We’ll talk again next time.
