This is a result of an attack to there stablecoin. I read some article on twitter thats shows how much the attacker spend just to depegged UST to its current price. The rest is just a panic sell same with LUNA. I think LUNA will revisit again it's original price which is below 1$ since the dev team is still silent and I doubt that they can present a emergency plan that minimize loss of there asset, investors already loss trust and price need to visit the strong support in able to bounce back again. I still believe on this project but I will not gonna buy at this sell pressure though.
