I have no problem with DOGE, but I think it won't change anything if the dev lists DOGE. Deposit and withdrawal via LTC is near free, so adding cheaper alternative is just too much work (with little impact).
I think that the added Deposit & Withdraw option using LTC is a win & win solution.
Doge is indeed one good choice, but with the price that is changing too fast at this time, maybe the dev will think more about adding the Deposit & Withdraw option with DOGE. It is only more profitable for the Player but very detrimental to Rollbit.
Yes indeed for now its a good choice while they don't add yet the other potencial coin which can make us save from those unacceptable fees taken from every transaction made by using bitcoins and ethereum. And as Doge is suggested by many user then its good to add since this really mean that people are using doge would love to gamble by using this coin.
