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.
beside that, the best thing that many people is invest into doge is they can use it for playing gambling, they only need to send dogecoin into their account and its no need to wait too long, the amount can arrive with fast. the other reason is i think dogecoin is for fun thing so they can save it into their wallet for long term investment.
