You're being paid 2.83% to absorb price risk. Only ~0.90% of it is real fees (the other ~68% is decaying emissions) — and they stop covering impermanent loss if USDC-WBTC-WETH diverges more than ±31%.
Real fee/staking yield: 0.90% · token emissions: 68% of the headline.
Break-even fact: a ±31% move in USDC-WBTC-WETH erases a full year of the fees you actually keep (~0.90%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
