PANews June 4 news, according to CCN, the scale of U.S. national debt has exceeded $37 trillion, raising concerns about the dollar's status as the global reserve currency. Coinbase CEO Brian Armstrong recently warned that if the U.S. cannot effectively control debt growth, Bitcoin may replace the dollar as the new reserve currency. This view is supported by Gemini exchange co-founders the Winklevoss brothers, who cited charts of the soaring U.S. debt and urged to 'buy Bitcoin.' Armstrong emphasized, 'I love Bitcoin, but a strong America is equally important to the world,' calling for fiscal reform. The debt ceiling 'X-date' is expected to arrive between late August and mid-October, and if the ceiling is not raised in time, the federal government may face spending cuts and payment delays.
