Facebook Unveils Plans For Its Own Cryptocurrency

To be sure, recent history reminds us that many big Facebook announcements never really take off. Two years ago, for instance, Facebook CEO Mark Zuckerberg promised that "augmented reality," in which phones and other devices project digital images into real-world surroundings, would be a major focus for the company. Such AR applications remain all but invisible today. Same goes for the online shopping chatbots that Zuckerberg unveiled a year earlier, saying they would revolutionize e-commerce in its Messenger app.
