Dogecoin is a clone of bitcoin which has achieved some success thanks to its innovative approach to marketing.
During the last year there have been more than a hundred new cryptocurrencies hitting the market, but it’s been rare for any of them to achieve wide recognition. In spite of this, Dogecoin has managed to make a name for itself by sponsoring numerous big-ticket events like the Winter Olympics and putting its name on NASCAR teams. Despite this big push, there still aren’t many places where you can actually spend the coin, so it’s turned into a kind of default tipping currency on the Internet.
100 billion coins had been minted by the close of 2014 and about 5 billion are being produced annually now.
