I completely understand why you don't want to send Huobi your personal information and ID. From there the question is, how much in funds do you have stuck in your account right now? You say a lot, but that's a pretty relative statement when it concerns your precious privacy. If the value in your account can't be missed, then you basically don't have any other choice than to verify yourself. Good thing however is that according to Huobi's terms, you can unbind your ID and your exchange account, which might be something for you to go through once you successfully managed to withdraw your funds. I however don't know if unbinding your ID and exchange account means they will actually delete everything related to you from their servers (I hope for you it does).
