I think doge is the best coin to play dice, because it's fast at transaction and easy to deposit or withdraw. Also the price is stable too.
Doge coin is the best coin out there to gamble when the price of bitcoin starts its rally and now a days almost all of the major gambling sites allow doge coin but none of the sports book have doge coin which is a real bummer, we need doge coin in sports book too so that people can gamble without using bitcoin and the price is really high to gamble with it.
Dogecoin started off as a ripoff of Bitcoin and its developer(Billy Markus) have stated multiple times that he is not serious about the coin. The positives is that it is having a large and loyal community of users, and the price per coin is low enough to be used in gambling. But if you ask me, I always prefer BCH or LTC ahead of Dogecoin.
