Because, Founder of Terra creator Terraform Labs, tweeted on Tuesday: “Close to announcing a recovery plan for $UST. And He Hangs tight On His Words.”
But in fact until now there has been no recovery. Only a madman builds his house well and then destroys it, then he will say he will rebuild it as before. People couldn't believe what he said, if it contradicted previous events.
It's a hoax. And he will create new hoaxes to cover up the previous hoaxes.
