You're being paid 0.31% to absorb price risk. Only ~0.31% of it is real fees — and they stop covering impermanent loss if BNB-USDT diverges more than ±17%.
Real fee/staking yield: 0.31% · token emissions: 0% of the headline.
Break-even fact: a ±17% move in BNB-USDT erases a full year of the fees you actually keep (~0.31%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
