The token DTB is traded on only two exchanges. You are planning a listing, if so, when it will happen.
There is no need for listing, the DTB is obsolete, they are selling game items for USD directly via app store.
I'm hoping that they do a SoG kind of release where you can buy the creatures outside of the game with DTB, expecting something like that for the Partners / Premium. There will need to be an outside the app auction house or swap bots.
