People who say they face troubles with KYC, later manage to pass it and withdraw their coins. Generally, that's it. Hitbtc should work faster but it's not a scam.
Well no. I am faced with forced KYC even though I requested to withdraw an amount much below their own limits for KYC. It just shows they are using KYC as a measure to slow down or in cases completely block withdrawals and this points directly to the issue of insolvency.
There are many exchanges who are slow to process KYC procedures but they do not force them on their clients when the clients try to withdraw limited amounts of money - HitBTC does, so it's an abnormal situation indicating they operate on illegally borrowed and in cases out right stolen money.
