Einsteinium (EMC2) coin was released in 2014. It is mineable and can be traded. You can also buy it in exchange for other cryptos (the buying option for fiat is not available yet).
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.
