Taking both risk of holding centralized stablecoin and the platform you stake only to earn 10%-15% per year is doesn't worth IMO. I'd say it's better for invest in banks and lock for around 3-5 years since it mostly give you around 5%-10% interest rate and there's a guarantee that your money will be back 100% because of insurance. Holding Bitcoin for long term are better option even though the risk is during dump market.
