MTC coin delisted in hitbtc? I'm not sure exactly what happened.
If I remember correctly then it got delisted from Hitbtc a few months later it got listed there, it happened due to what McAfee said to the HitBtc owner.
IMO currently the top exchange for DOC is Kucoin and in last AMA Charles said about listing in top exchange(s) by the end of Q3 or in Q4. It is not confirmed yet I guess.
