According to the link, USDD is not said to be algorithmic stable coin, or am I getting something wrong about it?
I guess the only way to maintain the peg would be to collaterize the stablecoin. USDD used to be a purely-algorithmic stablecoin, but after what happened with UST, it changed plans. It's now an "over-collaterized" stablecoin meant to give investors peace of mind. Whenever it'll hold its peg to infinity and beyond or simply fade into oblivion, it's yet to be seen. I think people are much safer cashing out their crypto to Fiat than putting all of their life savings in a stablecoin (especially algorithmic ones).
May the UST crash be a valuable lesson to all of those who're greedy. Always remember to never put all of your eggs in one basket, to avoid major losses in the long run. Who knows if algorithmic stablecoins become history in the not-so-distant future? Just my opinion
