Dogecoin was indeed born out of a joke, and that fun spirit lives on! But now, more and more people are beginning to realize the practical value of Dogecoin, and it has the potential to become a legitimate, efficient, and extremely practical currency.
Now, while keeping its fun spirit, Dogecoin has evolved into more than just "a joke". As the late, great Sporklin said, "Dogecoin can be a useful joke." Beneath the joke and meme-filled appearance of Dogecoin is the practical foundation that has been continuously consolidated since its birth.
Unlike other cryptocurrencies, Dogecoin has been very practical and has real-world applications since its inception. A few days after Dogecoin was launched in December 2013, a tipping program was created that allowed users to easily tip each other on reddit. For a long time, Dogecoin was used as a tipping currency on reddit because of its high transaction efficiency and low fees. During this time, the Dogecoin community also used Dogecoin to support some great causes and charities.
