What Is Dogecoin? Dogecoin (DOGE) is a peer-to-peer, open-source cryptocurrency. It is considered an altcoin and an almost sarcastic meme coin. Launched in Dec. 2013, Dogecoin has the image of a Shiba Inu dog as its logo. While it was created seemingly as a joke, Dogecoin's blockchain still has merit. Its underlying technology is derived from Litecoin. Notable features of Dogecoin, which uses a scrypt algorithm, are its low price and unlimited supply.
