Recently, everyone has been talking about sandwiches and arbitrage, and frankly, you think you've found an opportunity, but most of the time you're just helping others pay transaction fees and slippage taxes.

Now I see large on-chain orders, my first reaction isn't to "follow," but to look at the pool depth, whether the routing is taking a roundabout route, or if there are obvious trap signs...
Once the transaction price is pushed to an absurd level, don't expect yourself to be a hunter anymore.
Over on Layer 2, they’re constantly comparing TPS, fees, and subsidies, and it’s quite lively, but no matter how low the fees are, they can’t withstand being trapped every time, and the small savings are just given back.
Anyway, I treat complexity as an enemy: if I can set a limit order, I don’t use market orders; if I can split orders, I don’t go all-in; I’d rather earn less than become someone else’s fuel.
