Dogecoin was dead long time ago. It was never serious project as far as I know and noone treated as litecoin or ethereum. I wasn't even expecting to see people profiting out of it.
If it was dead ? Why is it still mined then. I think there are still people caring about Dogecoin. I agree that this coin has no future, but it still got the support from many people.
If it was a serious coin it maybe was succesfull.
