Elon Musk has sparked speculation that Dogecoin (DOGE) may have a future on Twitter's rebranded platform, "X," after adding an "X" and a "D" to his profile location. Observers, including Real Vision CEO Raoul Pal, believe Musk may use Dogecoin for global payments for creators on the platform. The speculation led to a small price gain for the memecoin, which rose as high as 5%. While the rebrand may provide a short-term rally for Dogecoin, eToro market analyst Josh Gilbert believes Musk's move could have significant long-term impacts on the crypto market.
