Elon Musk has warned of a looming "financial emergency" due to the growing U.S. national debt. Musk, who supports the use of cryptocurrency, believes the government's spending is unsustainable and has called for a more efficient system. He advocates for the "Doge Department of Government Efficiency," which he claims has saved billions of dollars. This comes as the price of dogecoin has soared, fueled by Musk's support and the potential for cryptocurrency to be used to reduce or even eliminate the U.S. national debt.
