Recently, someone said again, "Just put the coins in the pool and collect fees passively."

Every time I see that, I want to sigh...
The AMM curve is basically you passively rebalancing with the price—when it goes up, you're sold some; when it goes down, you buy more and more.
Impermanent loss isn't mysticism; it's built into the mechanism.
Whether the fees can cover it depends entirely on volatility and trading volume.
In a one-sided market, the busier you are, the more painful it gets.

And don't forget about the packing order nonsense:
You think you're a market maker, but sometimes you're just moving bricks for others and making space.
Slippage and getting squeezed, the experience feels very real.
Recently, the main public chain is upgrading/maintaining, and the group is guessing whether projects will migrate.
I think there's no need to rush after hot topics—first, understand the pool parameters, depth, and the volatility you can handle.
Anyway, I no longer believe in the phrase "passive income."
