If you stake your stable coins in liquidity, staking pools from providers that can be DeFi projects or cryptocurrency exchanges, you are no longer control your stable coins.
You are taking risk to lose your stable coins by staking. Celcius, Voyager, Three Arrows Capital bankruptcies are examples for that risk. I think you did not know about those companies and their bankruptcies because if you knew it, you knew about the risk and did not ask this question.
Bankruptcies, lose pegs, hacks, shutdown, many risks.
Stablecoins Are Not Worth the RiskIf you want to have passive income, pick savings in big banks.
If you want to take risk, pick Bitcoin and hold it in your non custodial wallets.
Don't take risk with stable coins.
