Recovery is definitely possible but it will take time especially after the Terra (LUNA) incident. Like other investments, the future of UST is uncertain and no one knows how it will turn out and maybe UST isn't over until it's finished. But I think it's a good bet, even now, for last a long time at UST.
Ust is minted from luna burning so how to recover when old luna token has been removed from exchanges and replaced by new luna token and the new luna has nothing to do with just. There are so many value tokens worth investing out there, why can't we just buy them. really ust is dead and nothing can be salvaged.
