In this case, those who bought the coin before the excessive issue occurred will suffer. I support such a plan, which was outlined by Do Kwon, the CEO of Terra creator Terraform Labs:
https://agora.terra.money/t/terra-ecosystem-revival-plan/8701, and is that it is necessary to roll back the blockchain to the moment when the issue of Luna amounted to $ 1 billion.
They could "rollback" to when things were good, but that doesn't mean that they will get what they wanted out of this. People should realize that they already spent so much to keep UST pegged, and that will result with a situation where people who ended up buying/selling during these past few days when it dropped to be angered, and anyone who will get it after the rollback will end up selling it as soon as it hits their pockets, so there is no scenario where it keeps high.
So, only reason Do Kwon even trying this is that he wants to print even more and try to keep UST pegged. If your system failed, it's failed, no reason to keep on trying it.
