Dogecoin (doʊʒkɔɪn DOHZH-koyn, code: DOGE, symbol: Ð and D) is a cryptocurrency featuring a likeness of the Shiba Inu dog from the "Doge" Internet meme as its logo. Introduced as a "joke currency" on December 8th 2013, Dogecoin quickly developed its own online community and reached a capitalization of US$60 million in January 2014; as of June 2017, it has a capitalization of US$340 million. Compared with other cryptocurrencies, Dogecoin had a fast initial coin production schedule: 100 billion coins have been in circulation by mid 2015 with an additional 5.256 billion coins every year thereafter. As of June 30th 2015, the 100 billionth Dogecoin has been mined. While there are few mainstream commercial applications, the currency has gained traction as an Internet tipping system, in which social media users grant Dogecoin tips to other users for providing interesting or noteworthy content. Many members of the Dogecoin community, as well as members of other cryptocurrency communities, use the phrase "To the moon!" to describe the overall sentiment of the coin's rising value. Thanks to crowdfunding efforts, a gold coin representing the cryptocurrency is scheduled to reach the Moon's surface in 2019.
