You're being paid 16.4% to absorb price risk. Only ~16.4% of it is real fees — and they stop covering impermanent loss if USDC-CBBTC diverges more than ±243%.
Real fee/staking yield: 16.4% · token emissions: 0% of the headline.
Break-even fact: a ±243% move in USDC-CBBTC erases a full year of the fees you actually keep (~16.4%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
