What are the uses of Doge?
Fast transaction, low fees, and stable altcoin (although this time Dogecoin gone wilder).
That's correct Doge is a meme and someone invest on Dogecoin just for memes thing. Beside that, traders who hold their coin on 2013 surely get profit from Dogecoin (2x or 3x). Because lots of supply that's really impossible to pass 1k satoshi.
