Lately, watching on-chain transactions feels a bit like checking the weather: the surface looks sunny (spread/yield) and quite tempting, but when you click in, it's all wind, slippage + sandwiches + people "collecting fees along the way." Honestly, you think you're arbitraging, but you might actually be working for someone else.

Recently, I keep comparing RWA, US Treasury yields, and on-chain yield products. My feeling is: those "yields" on-chain are often more than just interest; they’re like repackaged transaction friction sold to you under a different name. The more lively it gets, the easier you get caught.

My own clumsy way to prevent impulsiveness is simple: before placing an order, cut your expected profit in half, then add gas/slippage costs assuming the worst case. If it still looks worthwhile, then go ahead; otherwise, just close the page and go get a drink... Anyway, missing out is fine, and losing a bit of tuition is part of the game.
