Cryptocurrency requires an exercise in imagination: imagine a world in which money can be completely controlled by individuals, and sent globally cheaply and quickly. Imagine a world in which governments can’t inflate the money supply to fund their wars and ill-fated social programs. What makes cryptocurrency so exciting is that it truly has the potential to change how the world operates. Of course, the reason imagination is necessary is because we aren’t in that world yet: cryptocurrency is full of potential, and still short on delivery. But it’s important to engage the imagination to know where it is we’re going.
