I've been staking stablecoins on Binance and even though the rewards aren't much, they're passive income for me. There is no problem with the reward. I'm sure it will get bigger later because I do auto staking, where when I get the reward from staking, it will stake together in the next staking (correct me if I'm wrong). On Binance, there are several stablecoins you can use to generate more stablecoins and so far, I haven't had any issues.
If you compare the returns from staking and investing you will find that the profit earned is much lower than the return on investment, but if it is compared to the bank's interest rate you will see that it is not a small sum of money. In addition, investing is sometimes risky, not always profitable in the short term. If you have some idle money and do not want to risk investing it, then placing a stake may not be a bad idea for you.
