Facebook announced plans to launch a new cryptocurrency under a new subsidiary called Calibra. The not-for-profit Libra Association, which will oversee the virtual currency, launched Monday. Visa, MasterCard, PayPal, EBay, Stripe, and Mercado Pago, one of the biggest payment platforms in Latin America, also dropped out. Facebook CEO Mark Zuckerberg is scheduled to testify before Congress next week to address concerns about Libra, including protecting privacy. Facebook has tried to portray its cryptocurrency plans as a way to provide banking and financial services to a wide range of customers.”]
