This 1.77% is mostly real staking / lending yield (~1.70% of it). Only about 4% comes from token emissions. It is single-asset, so there is no impermanent loss to drag you below holding. It can still fall, but it isn't a disappearing subsidy.
Real fee/staking yield: 1.70% · token emissions: 4% of the headline.
No impermanent loss here — the ~1.70% is real income on the very asset you'd be holding anyway. Only any emissions portion fades.
