These days, someone asked me again, "If I just throw it into the pool, can I sit back and collect fees," and I just want to laugh... The AMM curve, to put it simply, is that the more it rises, the more you're selling, and the more it falls, the more you're buying. When the price fluctuates, impermanent loss quietly shatters your illusion of "beating holding" back to reality.

There are fees, but it depends on whether the volatility and trading volume are enough to offset them—don't just focus on the profit column.
Recently, Meme/celebrity calls have been rotating wildly; newcomers really shouldn't rush to be the last one, especially in pools: you think you're collecting tolls, but you're actually paying for the volatility.
What I fear most isn't missing out on opportunities, but making a impulsive move that turns principal into tuition.
