The first time I see on-chain "good prices flashing by," my initial reaction isn't opportunity, but that someone is pushing ahead of you in line—basically, with sandwiches, you think you're eating meat, but most of the time you're just the bread... Arbitrage is the same, on the surface it's about efficiency, but underneath it's a game of fees and priority.

Recently, the staking and shared security setups being called out as "nested dolls" I can really relate to: the compounded returns look attractive, but each additional layer adds a potential explosion point. When something finally goes wrong, the first to be drained are often those who believed most in the "certainty." Anyway, before I place an order now, I always check the slippage and pool depth first—better to earn a little less than to risk that piece of bread.
