Recently, memes have started to stir up again, with the group shouting about narrative and complaining "Why is on-chain so unfair," while also bringing up the issues of miner/validator income, MEV, and the sorting problems to vent.

Honestly, it's just lively entertainment. I set a rule for myself: as long as I can't clearly say who is paying for this wave of hype and who ultimately benefits (whether protocol revenue, buybacks, or governance proposals), I consider myself just fueling others.
So I set my stop-loss very ruthlessly — not waiting for "a feeling that something's off," but leaving the moment liquidity thins out and slippage starts biting, even if it continues to rise afterward, I count it as lost.
Anyway, I can't make all the money, so at least I won't be the last one holding the bag.
