You're being paid 2.10% to absorb price risk. Only ~2.10% of it is real fees — and they stop covering impermanent loss if BTC-USDC diverges more than ±51%.
Real fee/staking yield: 2.10% · token emissions: 0% of the headline.
Break-even fact: a ±51% move in BTC-USDC erases a full year of the fees you actually keep (~2.10%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
