Elon Musk plans to launch a limited beta version of "X Money" on X, a digital payment service linked with Visa, for peer-to-peer transactions. The challenges for widespread adoption include earning user trust and offering attractive features to encourage user migration from other services. Regulatory preparations for "X Money" are progressing, with licenses acquired in 41 U.S. states. The future integration of cryptocurrencies like DOGE remains uncertain, as X initially focuses on traditional financial infrastructure.
