You're being paid 4.10% to absorb price risk. Only ~2.75% of it is real fees (the other ~33% is decaying emissions) — and they stop covering impermanent loss if USDC-WBTC-WETH diverges more than ±61%.
Real fee/staking yield: 2.75% · token emissions: 33% of the headline.
Break-even fact: a ±61% move in USDC-WBTC-WETH erases a full year of the fees you actually keep (~2.75%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
