You're being paid 11.5% to absorb price risk. Only ~11.5% of it is real fees — and they stop covering impermanent loss if WETH-CBBTC diverges more than the pair moves.
Real fee/staking yield: 11.5% · token emissions: 0% of the headline.
The real fees here (~11.5%) can beat holding if WETH-CBBTC stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
