JPMorgan's says he regret calling bitcoin a 'fraud':

Chief Executive Jamie Dimon regrets calling bitcoin a 'fraud' but added that he still is not interested in the cryptocurrency at all, he said in an interview on Fox Business on Tuesday.
Dimon had called bitcoin a fraud at a bank investor conference in New York in September. "The currency isn't going to work. You can't have a business where people can invent a currency out of thin air and think that people who are buying it are really smart," he had said.
