"You got to understand where your yield comes from in DeFi. And if you don't, you are the yield." That line came up on Wednesday's group coaching call, and it's the whole lesson in one sentence. In this clip I take a real stretch of past market data and do the math out loud, so you can see why the fee number on a dashboard is only half the story. 🧮 The two numbers that matter When you provide concentrated liquidity (a CLP), you have two forces working on you: Theta = your fees. This is what you earn for keeping your liquidity in range while people trade through it. Gamma = your cost of volatility. This is your impermanent loss. And as a concentrated LP, your gamma is always negative. There's no situation where it works in your favor. It's always a cost. So the only question that matters is: did your fees beat your volatility? 📅 A historical example (past data, not a forecast) We marked out a 30-day window on an ETH/stablecoin chart, Sep 21 to Oct 21, 2026. Over that window ETH closed down about 9.8%. The fees earned by an LP position in an ETH/stablecoin pool over the same window came to about 3.19%. Fees look great on their own. Now do the subtraction: 9.8 minus 3.19 leaves you down about 6.61%. You earned fees the whole time and still lost money, because the market moved further than the fees could cover. ↘️ How you enter changes the damage The clip also covers why your entry matters. If you start 100% in a stablecoin and your range buys ETH on the way down while you earn fees, you end up down by about the gap between the move and your fees. If you enter 50/50, your impermanent loss is probably a bit larger. And if you had just held, you'd likely have been down by more. Same market, different outcomes, all because of how the position was built. 🔁 Why it's called "impermanent" If price comes back to your entry and you never closed the position, you've broken even on the capital you deployed, and you've kept the fees you earned along the way. The loss only becomes permanent when you close it while you're behind. That's the part most people never get explained to them.
