You're being paid 0.42% to absorb price risk. Only ~0.42% of it is real fees (the other ~1% is decaying emissions) — and they stop covering impermanent loss if USDT-WBTC-WETH diverges more than ±20%.
Real fee/staking yield: 0.42% · token emissions: 1% of the headline.
Break-even fact: a ±20% move in USDT-WBTC-WETH erases a full year of the fees you actually keep (~0.42%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
