Today about 9 hours ago I also had this KYC issue. Account is registrered 2 years ago but at that time I only made few transactions with them and it was about 2 years ago. Yesterday I made a deposit to Hitbtc for about 1100USDT, 9 hours ago tried to withdraw it and got a KYC request from them. I uploaded pictures of my drivers licence, selfie, name, address and phone number. I didn't write them anything about that and decided to wait. Now 9 hours later my account is verified and made another withdraw to Binance and it also arrived. So I would not say that Hitbtc is a scam.
