You're being paid 6.87% to absorb price risk. Only ~6.87% of it is real fees — and they stop covering impermanent loss if GTR-USDC diverges more than the pair moves.
Real fee/staking yield: 6.87% · token emissions: 0% of the headline.
The real fees here (~6.87%) can beat holding if GTR-USDC stays calm, but a sharp divergence flips that. It's a genuine short-volatility bet, not free income.
