币界网报道：Billionaire investor Ray Dalio warns the US economy could face a "serious economic heart attack" within approximately three years, citing unsustainable debt levels and political polarization. The Bridgewater Associates founder highlights that the Federal Reserve's current monetary policies may not effectively address structural issues, including rising inflation and fiscal deficits. Dalio emphasizes that the US dollar's reserve currency status could weaken if these challenges persist, potentially leading to a broader financial crisis. He advises investors to diversify portfolios with assets like gold and cryptocurrencies as hedges against economic instability. Dalio's comments come amid growing concerns over global economic slowdowns and increasing debt burdens across major economies.
