Following months of outcry about the unsustainable nature of Terra Luna, Do Kwon through his foundation tried to partially collateralize the stablecoin with bitcoin, with a goal of buying up to $10bn of bitcoin. He got $3-5bn (at the time, price changed a lot), and this prolonged the confidence system for one additional month.
And then it imploded and sold the collateral, of course it was partial collateral so it failed to do anything in a bank run.
So it doesnt matter whether we get records from exchanges or not. Nothing different would happen. People want to see Do Kwon have more reasons to have charges against him, but there’s no need to attribute it to malice, everything can be explained by incompetence already.
