Dogecoin, the cryptocurrency inspired by the popular internet meme of a Shiba Inu dog, surged by over 30% on Sunday after Twitter changed its logo to the dog's symbol. Social media users speculated whether the move was a nod to Dogecoin or merely a coincidence. In recent months, Dogecoin has gained popularity, with endorsements from Tesla CEO Elon Musk and rapper Snoop Dogg. The cryptocurrency's price has soared, reaching an all-time high of $0.0871 earlier this year. However, critics have warned that Dogecoin's value is purely based on hype and speculation, and it lacks the technical sophistication of other cryptocurrencies. Twitter's logo change is the latest in a series of events that have boosted Dogecoin's public profile.
