You're being paid 20.8% to absorb price risk. Only ~20.8% of it is real fees — and they stop covering impermanent loss if USDT0-WETH diverges more than ±314%.
Real fee/staking yield: 20.8% · token emissions: 0% of the headline.
Break-even fact: a ±314% move in USDT0-WETH erases a full year of the fees you actually keep (~20.8%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
