U.S. and Canadian customers of failed Tokyo-based bitcoin exchange Mt. Gox have agreed to settle their proposed class action lawsuits that alleged the company defrauded them of hundreds of millions of dollars. The class action plaintiffs agreed to support a plan by Sunlot Holdings to buy the shuttered exchange and accept their share of bitcoins still held by Mt. Gox, according to a statement and court filings. Mt. Gox filed for bankruptcy in Japan and the United States earlier this year after saying it lost some 850,000 bitcoins - worth more than $400 million - in a hacking attack. It subsequently said it found 200,000 bitcoins. Once the world's biggest bitcoin exchange, Mt. Gox is slated to be liquidated after the Tokyo District Court granted the company's request to abandon plans to revive its business.
