Dr. Doom: Libra is not a cryptocurrency, nor a blockchain

At the 2019 Asian Blockchain Summit in Taipei yesterday, BitMEX CEO Arthur Hayes expressed optimism about Facebook's Libra, saying it could benefit billions of people around the world. Dorothy Dr. Nouriel Roubini countered that the payment system revolution has taken place and that these crappy cryptocurrencies can be replaced in the future by using a "zero cost" payment method. Libra is central, not a cryptocurrency, nor a blockchain, but it is stronger than all junk coins in terms of potential and scalability.
