You're being paid 8.29% to absorb price risk. Only ~5.02% of it is real fees (the other ~39% is decaying emissions) — and they stop covering impermanent loss if USDC-CBBTC diverges more than the pair moves.
Real fee/staking yield: 5.02% · token emissions: 39% of the headline.
The real fees here (~5.02%) can beat holding if USDC-CBBTC stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
