Dogecoin is looking like a scam with strange name and almost free coins. At my opinion no future for this cryptocurrency because competition is to high nowadays.
It seems a bit negative here, I just feel it does not have the necessary traits, because of the platform combination from Litecoin and Bitcoin. It's like an exaggeration. So, they choose independent direction in a fun and just use as a tool to buy fun for the community. It may not have much sense of competition for strong growth in the future. I believe in Ripple and NEO more.
