I would not risk the whole coin on gambling - and not on dices. Actually, I am in no position to advise you to use dices or not, since I haven't ever played it before. I would rather use some on sports book if you do have tried it before with success - as one of the other suggested, you could loan some of the coin to others, it seems the interest rates are quite good. Or you could simply just keep it, and then eventually cash out when it reaches x amount of value.
