Sirob Correct, withdrawal any time without penalty. Risk-off, blue-chip platforms, decentralized and permissionless. AFAIK Nexo isn't decentralized & non-custodial, they are more of a fiat on-ramp to defi?
The new NEXO bridge pools have like 17%, yeah, there're certainly more rewards out there - but come with priced-in risks as well.
Main hope here is just to whitelist a non-controversial, widely accepted top-performing platform, time-tested and rigorously audited, so we can not worry about risk while we devise a strategic deployment of this USDC.
