Back in September 2017 Dimon angered the cryptocurrency world by calling bitcoin a "fraud" and said "if you're stupid enough to buy it, you'll pay the price for it one day,"Regarding those comments now - he says "I regret making them" in an interview on Fox Business.But Dimon wasn't all cheer about Bitcoin, and also added he worries about how "governments are going to feel about bitcoin when it gets really big." To be fair, a concern shared even by Bitcoin lovers.Dimon's earlier comments had seemed to be at odds with his own company for months. In October JP Morgan Chase announced they would be using blockchain technology to speed up their global payments in a project called "Interbank Information Network" and said the tech would increase the speed of these transactions "from weeks to hours."It seems Dimon is becoming a believer, slowly.-------
