You're being paid 18.5% to absorb price risk. Only ~18.5% of it is real fees — and they stop covering impermanent loss if USDC-WETH diverges more than the pair moves.
Real fee/staking yield: 18.5% · token emissions: 0% of the headline.
The real fees here (~18.5%) can beat holding if USDC-WETH stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
