Did terraform Labs co-founder do Kwon convert illicit funds into bitcoin?

I'm curious, could you clarify for me if Terraform Labs' co-founder, Mr. Kwon, has indeed been involved in converting illicit funds into Bitcoin? Is there evidence that suggests he used his position to engage in such unethical financial practices? What steps, if any, have been taken to investigate these claims? Given the nature of cryptocurrency transactions, would it be difficult to trace such funds if they were indeed converted to Bitcoin? And what implications does this have, if proven true, on the cryptocurrency market and its regulatory frameworks?
