You're being paid 5.20% to absorb price risk. Only ~4.34% of it is real fees (the other ~17% is decaying emissions) — and they stop covering impermanent loss if YMVDG-USDC diverges more than ±82%.
Real fee/staking yield: 4.34% · token emissions: 17% of the headline.
Break-even fact: a ±82% move in YMVDG-USDC erases a full year of the fees you actually keep (~4.34%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
