These guys are a pure scam. I sent to my account 1 Ethereum on the 28th of December. I have a confirmation they received it. My account it not credited and they are not responding to my emails or tickets for 18 days now. "Eugene Moura (HitBTC)" <support@hitbtc.zendesk.com> this guy responded that my issue got escalated to 2nd level support and nothing since then for 18 days I waiting for the 2nd level support to tell me what happened to my deposit.
