Update: I answered their questions and I'll say that I was not very specific at all. I said that I received the coins after a relative said he'd invest some of my spare cash into bitcoin for me. After that, the withdrawal of roughly $80k USD was successfully wired into my bank account. I only had to wait a week.
It's good to know it worked out ok for you, but I hope someone can find out if they would allow one to trade back to BTC and withdraw that without satisfying all their questions.
