PANews reported on May 17 that according to Coindesk, Moody's downgraded the US sovereign credit rating from "Aaa" to "Aa1", becoming the last of the three major credit rating agencies to remove the top AAA credit rating in the United States. Affected by this, the cryptocurrency market fell along with the stock market, triggering risk aversion and new concerns about government debt and macro stability.
