Someone just said "On-chain is the fairest market," and I almost burst out laughing... MEV, to put it simply, is just cutting in line and pushing ahead: you think you're trading in order, but someone slips in front of you, taking a bigger slippage, canceling late, and the hurt mostly falls on ordinary people clicking manually. Arbitrage is said to be "providing efficiency," I get that too, but every time I get squeezed, my mood cracks, especially when chasing memes—when a celebrity calls out, attention shifts, and newcomers rush in, it feels more like being treated as liquidity... Veteran players really advise not to take the last baton. As for me? When I get excited and want to add to my position, the on-chain world immediately teaches me a lesson. Forget it, I’ll just reduce my position today. You say "then use private orders/protection"... I'll just say first: I’m too lazy to bother.
