Last night I stayed up until 2 or 3 a.m. again, watching on-chain "queue jumping"—it's really quite annoying: you just click confirm, think you're the first to arrive, but then someone pushes you to the front, and when you slide your point up, the losers are basically small manual traders. To put it simply, MEV isn't just about snatching money out of thin air; it's more about turning the originally random order into whoever can snatch better or is willing to bid higher gets to eat first, and the sense of fairness is directly eroded.

My mom also asked me, "Aren't you guys queuing when buying coins? How can there be queue jumping?" I could only reply half-heartedly: on-chain queuing isn't based on arrival time, but on who gives more to the miners/packagers... sounds ridiculous, but that's the reality.

Recently, hardware wallets are out of stock again, phishing links are everywhere, everyone's security awareness has improved, but the trading experience is really stuck on both ends: one side fears clicking the wrong link, the other fears being squeezed in the middle and getting cut. I still experiment with small amounts; if I really want to go all-in, I treat it as tuition first, and if I lose, I’ll write a post reviewing the experience. For now, that's how I do it.
