I think what Dogecoin needs is more adoption to actually buy things with it. Devs should also think about getting the coin accepted by more retailers together with adding new features.
I think that the biggest problem of Dogecoin is a supply . Which is definitely too big. If there would be 60M things with the value would be different.
But ... at least now have a lot of Dogecoin millionaires
True, so many coins will bring the value down. But at least if they could be spent to buy something, wouldn't that be better?
When we look at Darkcoin and the masternode function. The implementation is more an issue than something really useful, and operational. The only goal they have in mind is to get for free 20% of the new coins generated by the POW. Dogecoin has no scam feature, and is well supported and known, It may come back and get all the attention.
