币界网报道:On June 12, according to the Wall Street Journal, Jeffrey Gundlach said on Wednesday that the US debt burden and interest expenses have become "unsustainable", which means that long-term US bonds are no longer considered a truly risk-free investment. He compared the current market environment to the situation before the bursting of the Internet bubble in 1999 and the global financial crisis in 2006 and 2007. He said that investors should consider increasing the allocation of non-US dollar assets and revealed that the company he manages is beginning to include foreign currencies in its funds.
