Lately, I've been watching the excitement around on-chain sandwich attacks and arbitrage, to be honest, I’m increasingly unable to tell if I’m "seizing opportunities" or just paying others' fees. Especially when some pools quietly change their fee rates and slippage parameters; a quick comparison screenshot makes it very obvious. Ordinary people following the old knowledge to place orders are basically getting caught in the middle.

The current practice of staking again and sharing security for "compound yields" is also being criticized as a copycat scheme. I can understand why; the more layers there are, the more each layer has to take a cut, and in the end, all that’s left for the user is just a heartbeat. Anyway, my current approach is pretty cautious—I prefer to make fewer moves rather than become fuel in a bunch of invisible priority queues.
