About 52% of this 5.12% APY is decaying token emissions. The real staking / lending yield is ~2.48%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 2.48% · token emissions: 52% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~2.48% of real yield — the rest is fading emissions, not income.
