You're being paid 2.43% to absorb price risk. Only ~2.43% of it is real fees — and they stop covering impermanent loss if USDC-CBBTC diverges more than ±56%.
Real fee/staking yield: 2.43% · token emissions: 0% of the headline.
Break-even fact: a ±56% move in USDC-CBBTC erases a full year of the fees you actually keep (~2.43%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
