You're being paid 2.51% to absorb price risk. Only ~2.51% of it is real fees — and they stop covering impermanent loss if CRVUSD-WBTC diverges more than ±57%.
Real fee/staking yield: 2.51% · token emissions: 0% of the headline.
Break-even fact: a ±57% move in CRVUSD-WBTC erases a full year of the fees you actually keep (~2.51%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
