Dogecoin will be used a lot but you can't have a big profit from it. I had also dogecoins, but for me they were worthless thats why I have sold them. I just simply couldn't make a profit.

There was also a thread that says can dogecoin go to 1 cent. I think not because its never been close to that. So for me it has no future, but some other people will still use it like for mining.
