It's here, but I can't seem able to find how to use it
I'm also in this same situation; I recovered one of my old accounts sometime in early February and saw the same amount of dice, which were worth the same volume in bitcoin, but there is no means of trading it.
Even when I tried to reach out to support, no response was given. I think the said token was an airdrop, which has now been delisted from the exchange, and the value we might be seeing now should be what the token was last traded as before it was delisted.
