You're being paid 27.5% to absorb price risk. Only ~27.5% of it is real fees — and they stop covering impermanent loss if NES-USDC diverges more than ±443%.
Real fee/staking yield: 27.5% · token emissions: 0% of the headline.
Break-even fact: a ±443% move in NES-USDC erases a full year of the fees you actually keep (~27.5%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
