The idea of using the DAI stablecoin is specifically because it has
low volatility. This allows you to have peace of mind knowing the value of the coin will be similar 1 week from now as it is today. This is similar to what fiat tries to do. In addition, you can earn more or less guaranteed interest without worrying if your coin's value will drop suddenly.
Not new anymore some market are offering the same with their stabelcoin products. Maybe this one is more focus on dai, but I better not base on this earning style which give you a very small profit. Better yet to do trading, or any lending platform with conservative and much more higher interest.
Binance doing this and they also have saver program well you literally hold your coin and even stablecoin of usdt and you earn passively. For me its better cause it is trusted than this.
The reason I suggest avoiding such solutions is that you do not have custody over your funds, Binance does. As the saying goes,
not your keys, not your coins. Therefore you are not your own cryptobank but rather you switched from one bank to another.
