If they have stopped trading with the coin you mentioned there is nothing you can do, looks like you will be a bag holder for the rest of your life, i am sure the exchange will allow you to withdraw those funds to your own wallet before removing the coin entirely, i am not sure which coin you are talking about as i could not find that in coinmarketcap.
It's a dying coin
(or should I say already dead) for quiet period of time. Obviously it won't appear in Coinmarketcap now.
Yes as always exchanges will allow withdrawal of a delisting coin. But after the timeframe given and no withdrawal from the part of the user have been done, the coins are gone for good although it's fine rather than to become a designed in a user's own wallet. I doubt developers of that coin will come back and will attempt to revived it.
