They need to talk with Cryptopia. 

Cryptopia closed down the LTC/DOGE markets.

Dentacoin can only be traded on those markets.  The withdrawal fee to another market is 14,000 Dentacoins. 

So.....I have 150k Dentacoins I bought way before the hype.....and now to access it I have to give up all those gains on 14,000 coins.

Crap.
