Dogecoin (DOGE) was founded in the US in 2013 as a joke but quickly gained a large following. It became a popular cryptocurrency (DOGE) used for tipping the content creators (mainly on Reddit and Telegram). As the creators had no serious plans for their currency they didn't elaborate a roadmap and were not working on the improvement of their project too much. The founder of Dogecoin Jackson Palmer left the project in 2015.
