Just doing that on-chain "sandwich + arbitrage" operation, honestly, you think you've caught an opportunity, but often you're just giving others transaction fees... I've seen the floor suddenly get swept, liquidity shake, and my hand tremble as I chase after it, only to realize at the moment of execution: I’m like an automatic recharge machine. Recently, before and after the upgrade/maintenance of that mainstream public chain, the group has been guessing whether projects will migrate, and I dare not move recklessly anymore. I'm more afraid of chaos than slowness — a slower pace still allows for clearer thinking, but when things get chaotic, you can't even tell if you're losing money on the price or on slippage. Anyway, I now prefer to wait and buy at a lower price, rather than racing against those flickering "opportunities."
