 Dogecoin was introduced on December 6, 2013 - 0x2013126

 Dogecoin (/ˈdoʊ(d)ʒkɔɪn/ DOHJ-koyn or DOHZH-koyn, Abbreviation: DOGE; sign: Ð) is a cryptocurrency created by software engineers Billy Markus and Jackson Palmer, who decided to create a payment system as a joke, making fun of the wild speculation in cryptocurrencies at the time.
 
 It is considered both the first "meme coin", and more specifically the first "dog coin". Despite its satirical nature, some consider it a legitimate investment prospect. Dogecoin features the face of the Shiba Inu dog from the "doge" meme as its logo and namesake.
 It was introduced on December 6, 2013, and quickly developed its own online community, reaching a peak market capitalization of over US$85 billion on May 5, 2021. As of 2021, it is the sleeve sponsor of Watford Football Club.
