About 80% of this 11.9% APY is decaying token emissions. The real staking / lending yield is ~2.39%. It is single-asset, so there is no impermanent loss to drag you below holding.
Real fee/staking yield: 2.39% · token emissions: 80% of the headline.
No impermanent loss here, so you keep the same price exposure either way. The honest number is the ~2.39% of real yield — the rest is fading emissions, not income.
