UST issue is an isolated case. They implemented a plausible protocol which destroy the value of there stablecoin. All stablecoin that affected by the UST fud before already recovered and pegged to $ at this moment. I don’t see any risk or danger of staking stablecoin right now and I think UST kind of incident will not gonna happened to all existing stablecoin that running for a long time like USDC and USDT.
