Before I can withdraw my coins even my account is not verified?
So right now, your account should be KYC'ed before you can withdraw?
According to this
https://hitbtc.com/verification-general you have 1BTC daily and 5BTC monthly for non-verified users but I heard you can't be able to withdraw any amount if you are a not-verified user.
So, I think you should be KYC verified before you can able to withdraw any amount, it's their process of checking real users, and to avoid money laundering.
