Yes, they are a SCAM. They block bigger withdrawals and force bogus KYC procedure to stall. People report waiting for their money for months without any success or response by the staff.
In short, they are stealing users funds' whenever possible.
They arent still scam yet they are still operation and just like Yobit they are shady as hell. Holding users funds and shady alibis on stealing peoples money.
I used up Hitbtc and withdrawals comes through without any issues but their fees are insanely high which havent being changed ever since as i remember
wayback on that 2017 bull run.
