I think its inevitable with such case of terra ust. Their apy is really high compared to other stablecoin and thats make it more quite risky. Of course I hate to say it, that I am one of victim of it but other stablecoin too lack audit. Cant say that its a failed experiment but the lack of sufficient security measures were missed on this. Whales have managed to outrace them using their fund and thats the weakness they exploited. Decentralized or not once someone realize a flaw then it will literally be a bad result on the other end.
