Dogecoin was created in 2013. It was originally a "joke coin" created to mock the cryptocurrency investment boom. It uses the Shiba Inu as its logo and is full of fun. It is based on the Litecoin algorithm, has no upper limit on the total amount, is issued quickly and at low cost. Compared with Bitcoin, Dogecoin has a short transaction confirmation time and low transfer fees. Due to the spread of social media, Dogecoin's popularity has soared rapidly. The support of some celebrities has made it even more popular, and its price has fluctuated violently. Although it has entertainment attributes, it has also occupied a place in the virtual currency market. However, virtual currency investment is high-risk, and Dogecoin transactions are also subject to the risks of regulation and large price fluctuations.
