With how shady Justin Sun's actions are, I would steer clear from USDD as much as possible. The stablecoin is still driven by algorithms even though Justin Sun claims it to be "overcollaterized". This term may just be a marketing scheme to attract as much investors into the stablecoin itself. I can't imagine how big the market crash will be if USDD loses its peg for a long period of time. Investors will be so angry they'll probably ditch stablecoins altogether. Regulators need to weigh in on the industry to prevent another downfall of such magnitude.
With how bad things have turned out for algorithmic stablecoins, it seems to me that only truly collaterized stablecoins will survive. I'm fine with that as long as decentralized cryptocurrencies remain the leading force of the industry. Just my opinion
