Dogecoin was created in 2013 as a 'joke coin' to mock the cryptocurrency investment craze, featuring the Shiba Inu as its mascot and full of fun. It is based on the Litecoin algorithm, with no upper limit on total supply, fast issuance speed, and low cost. Compared to Bitcoin, Dogecoin has a shorter transaction confirmation time and lower transfer fees. Due to the spread on social media, Dogecoin's popularity surged rapidly, and support from some celebrities made it even more prominent, with significant price fluctuations. Although it has entertainment attributes, it has also carved out a place in the virtual currency market. However, investing in virtual currencies carries high risks, and Dogecoin transactions also face regulatory risks and significant price volatility.
