Speculations have arisen about Elon Musk's potential use of Dogecoin (CRYPTO: DOGE) for global payments on Twitter's rebranded platform, 'X'. Macro Guru and former Goldman Sachs executive Raoul Pal suggested that Musk might use Dogecoin as a medium for global payments to content creators on the platform. This speculation was fueled by changes in Musk's Twitter bio, which now includes an 'X' and a 'D', interpreted as references to Twitter's rebranding and Dogecoin respectively.
