I do not know why would you even compare the two, those two are not comparable. But if I will choose, obviously I will choose bitcoin over dogecoin. The value of bitcoin is way more higher than doge, 1 btc is equal to around 7500 us dollars, dogecoin's value is equal to 0.001172 us dollars or just basically nothing compared to bitcoin.Dogecoin is also used in in videogame purchases. I prefer dogecoin only just for the fun because I think it is one of the reason why dogecoin was created,  to be the "fun cryptocurrency". I am looking forward to the future of dogecoin, much money such wowe.  But overall my choice here is bitcoin.
