why don't you do it via bank deposit. I mean stablecoin staking will generate similar amount of income from staking. If you compare to some countries, bank deposit will fetch much higher return than staking. Yes there are some exceptions for sure but the credibility of those coins is questionable.
There are many risks like, de-pegging of price, staking platform may disappear, lock up period etc. I personally wouldn't do staking with a lock in period.
Yeah, if you put dollars (or your fiat of preference) into a bank as a savings account, it will definitely get money and then give money, and that should not be all that complicated. The thing is, stablecoins and staking them, do not bring anything better than banks and their savings accounts, so the idea doesn't seem like a good one for me. Specially if you consider putting some trusted stock as well, not sure what they call them, vanguard or something?
Whatever it is, like group of stocks, and you make some good return, while keeping it fairly safe, and depending on how stock market does, you may earn a ton. That is even better. Stablecoin staking seems like very low return of investment ,compared to the risk you are taking when you do that.
