Dogecoin is a cryptocurrency that started as a joke in 2013, featuring the popular Doge meme of a Shiba Inu dog. It was created by software engineers Billy Markus and Jackson Palmer to provide a fun and friendly alternative to more serious cryptocurrencies like Bitcoin. Despite its humorous origins, Dogecoin has gained a large following and is used for tipping content creators online and for charitable donations. Its community is known for being supportive and engaging, often participating in various fundraising efforts and events to promote the coin's use and visibility.
