Just check hitbtc reddit and you don't want to deal with them. If they block you, get ready for verification in the FBI style, which will last for months with no result. They will demand more and more new evidence from you until they find something that you cannot provide.

They blocked more than 10000$ dollars just now and now they require 1000 different documents / evidence that I am not a criminal.
