HITBTC no longer trades docacademic. They became angry after a tirade of John McAfee. What you need to do is ask HitBTC to release your MTC tokens so that you can send them to your own wallet. For example Metamask. If you have them in there you will also receive the airdrop from Docacademic, but then you have to register your ethereum address! (see https://www.youtube.com/watch?v=dIn-XV5dVhE). You will not receive them if you have them on an exchange. Succes
