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.
Doge is pretty good but don't forget Litecoin. It is pretty fast and solid as well.
Bitcoin became just like real gold. You don't use gold to buy groceries and you shouldn't spend Bitcoin on cheap stuff neither. Hopefully LN will make BTC to function as a currency again. Till it happens, use either LTC or Doge.
