Dogecoin is an open-source digital currency, which is initially introduced by programmer Billy Markus. It has become famous cryptocurrencies with its low fees, fast transactions, stable inflation rate and has been officially passed the one billion market cap barrier.
Dogecoin has been used as a payment form in many cases such as the weather forecasting website, some people would allow viewers to visit her website by setting up Dogecoin payment system; the internet currency has been used in gambling and the Sun-Times Media Group has reportedly planned to implement dogecoin tipping for its writers
While some people think that dogecoin is worth almost nothing and consider it as 'joke coin', one should bear in mind that bitcoins also used to be worth nothing several years ago. I believe that Dogecoin will become the next Bitcoin as it has drawn many attention.
