text:  The exiled Chinese businessman, Guo Wengui, has been convicted by a U.S. court of stealing hundreds of millions of dollars from online followers. Federal prosecutors said Guo had raised more than a billion dollars by guaranteeing that backers would not lose money if they joined him in a series of investment and cryptocurrency schemes. He promised that some of the profits would be used to attack the Chinese government. Instead, the money was used to fund a lavish lifestyle.
