Dogecoin is an open-source peer-to-peer digital currency that prides itself on its vibrant online community of users. It was first introduced as a “joke currency” but then later turned into a legitimate cryptocurrency. Dogecoin has over 20 billion coins in circulation, much more than other coins which usually only number in the millions. The community has undertaken various fundraising projects such as sponsoring Winter Olympics competitors, “Charity: Water” in Kenya and a NASCAR driver. It is also popular for its tipping system by which users can tip others who they want to reward for good social media posts. Transaction speed and volume are a strong point of Dogecoin, with it currently holding the record for the most transactions performed in a day by a cryptocurrency. Dogecoin (DOGE) is the coin that can be sent over the Dogecoin blockchain.
