My take on this subject, I believe there is not only one person who owns this wallet. Maybe a group of individuals who in one way or another are trying to move their holdings to prepare for something big. If that big amount comes from huobi, more than likely that person who is currently managing that account has done the kyc stuff but the question is, if he is using legit docs. The exchange might have the information but who knows if they will ever disclose the owner of that address even if authorities are hunting them down.
It's now the job of huobi or whoever is/are responsible for monitoring and verifying that account through the generated address from their exchange.
And it's not our problem anymore if the verification has passed or if the owner just asked other people to verify the account. I think there will be news few days or weeks from now and there will be someone claiming this transaction.
