doge coin is not fasted than xrp. xrp deposits in micro seconds. every gambler needs a coin that deposits so fast. doge is good but it is not as fast as xrp. my only issue with xrp is that i have to copy the tag.
XRP might be faster then dogecoin. But Dogecoin is also too fast and its fee is almost 0. 1/2 doge from the main wallet though few exchanges may take more fee. Maximum gambling site also take small fee. Dogecoin is easy to transfer then XRP.
