In 2017, a little-known cryptocurrency called Dogecoin surged in value by over 11,000% in just a few months. Dogecoin was created as a joke, featuring a Shiba Inu dog from a popular meme. However, it gained a loyal following and even attracted the attention of Elon Musk, who tweeted about it several times. This helped to fuel Dogecoin's meteoric rise, but it also led to a speculative bubble.
