I do not think this coin has any future except pure trading speculations mainly pump and dumps. Dogecoin as a coin I do not really see it growing much but there used to be Dogecoin Dark which is now Verge and its doing pretty well.
We never know, as long as there is always a volume we can expect big surprise in the future to come.
The market will get bigger and we will see new investors coming in, Doge is in top 50 so it can easily be notice by potential investors.
