Any drawback/weakness of double token stable coin compare to fiat money back stable coin like USDT?
Well, USDT is extremely easier to implemented because it's centerlized service. Otherwise, I don't think there is any drawback/weakness for this kind of project over USDT or TUSD.
I'm thinking that money-wise; fiat-back stable coin is less risky in case of crypto currency crashing. In this sense, USDT holders basically still can claim back equivalent dollars when the crypto space disappear. What do you think about this?
