Bitcoin, the digital currency, was introduced in 2009 with little fanfare; five years later, shocking the world, it was worth $14 billion. This book explores the cyber currency by focusing on the remarkable stories and intriguing personalities of those responsible for its sudden success: Satoshi Nakamoto, the reclusive and anonymous genius who created Bitcoin; Ross Ulbricht, aka the Dread Pirate Roberts, administrator of the largest and most successful Dark Web drug superstore, using Bitcoin to fuel online sale of drugs, hacking services, counterfeit money, and assassinations; and Cameron and Tyler Winklevoss, Harvard graduates, successful litigants vs. Facebook, world-class Olympic rowers, and Bitcoin entrepreneurs who own 1 percent of all bitcoins in existence. Equal parts The Social Network, Sherlock Holmes, and Breaking Bad, this absorbing narrative tells the stories of the reclusive genius who waged a one-man war against the global banking system (and he's winning); the quiet and affable computer geek who, until his arrest, profited handsomely from Silk Road, his online drug superstore; and the multitalented Harvard twins, who made a fortune from an intellectual-property suit against Mark Zuckerberg, and now are the chief promoters of Bitcoin as "the next big thing." Bitcoin has introduced us to coke-fueled coding gurus, anger-crazed hitmen-hiring millionaires, and canny "Bitcoin miners" avidly adding processing power to their chilly Icelandic server farms to generate millions of dollars every month. Absurd and almost unbelievable stories abound, and sweep the reader along through the living and breathing, passionate and paranoid insiders who made it all happen.

THE GUIDE TO USING EVERYDAY TECH—FROM GOOGLE SEARCHES AND AMAZON TO GPS AND FACEBOOK—WITH EYES WIDE OPEN. What if somebody knew everything about you? Your . . . • relationships: work, social, and private • family history, finances, and medical records • even your exact location . . . at any time of the day • personal preferences and purchases Somebody does. That somebody is “Big Tech.” Facebook, Google, Amazon, Apple, and Microsoft know more about you than you do. And they make billions of dollars by cashing in on your private data. Our personal data, which Big Tech companies get for free, is the engine that drives the unregulated, free-for-all, Wild West world called the digital marketplace. These corporate giants may bring us information and entertainment, convenience and connection, but they also do a lot of harm by: • threatening our privacy, discovering and disseminating our personal information. • spreading dangerous misinformation from foreign governments and bad actors. • manipulating our behavior, affecting what we see, buy . . . even who we vote for. So, what can we do about it? This eye-opening book provides vital information that has been out of reach to those who need it most—the millions of Facebook, Google, Amazon, Apple, and Microsoft users who have come to love and depend upon these digital products. Veteran consumer advocate Jane Hoffman makes the complex world of Big Tech simple to grasp as she reveals exactly how Big Tech uses—and abuses—your personal information. And she proposes a bold blueprint for reforming these corporate behemoths—including a data dividend. Your Data, Their Billions is a guidebook to everything at stake in our digital society, from Big Tech’s overreach into our daily lives to its practices that threaten our democracy. Knowledge is power—and it starts here.

A fascinating exploration of the history, development, and future of virtual reality, a technology with world-changing potential, written by award-winning journalist and author David Ewalt, stemming from his 2015 Forbes cover story about the Oculus Rift and its creator Palmer Luckey. You’ve heard about virtual reality, seen the new gadgets, and read about how VR will be the next big thing. But you probably haven’t yet realized the extent to which this technology will change the way we live. We used to be bound to a physical reality, but new immersive computer simulations allow us to escape our homes and bodies. Suddenly anyone can see what it’s like to stand on the peak of Mount Everest. A person who can’t walk can experience a marathon from the perspective of an Olympic champion. And why stop there? Become a dragon and fly through the universe. But it’s not only about spectacle. Virtual and augmented reality will impact nearly every aspect of our lives—commerce, medicine, politics—the applications are infinite. It may sound like science fiction, but this vision of the future drives billions of dollars in business and is a top priority for such companies as Facebook, Google, and Sony. Yet little is known about the history of these technologies. In Defying Reality, David M. Ewalt traces the story from ancient amphitheaters to Cold War military laboratories, through decades of hype and failure, to a nineteen-year-old video game aficionado who made the impossible possible. Ewalt looks at how businesses are already using this tech to revolutionize the world around us, and what we can expect in the future. Writing for a mainstream audience as well as for technology enthusiasts, Ewalt offers a unique perspective on VR. With firsthand accounts and on-the-ground reporting, Defying Reality shows how virtual reality will change our work, our play, and the way we relate to one another.

The first edition of BANK 2.0—#1 on Amazon's bestseller list for banking and finance in the US, UK, Germany, France, and Japan for over 18 months—took the financial world by storm and became synonymous with disruptive customer behaviour, technology shift, and new banking models. In BANK 3.0, Brett King brings the story up to date with the latest trends redefining financial services and payments—from the global scramble for dominance of the mobile wallet and the expectations created by tablet computing to the operationalising of the cloud, the explosion of social media, and the rise of the de-banked consumer, who doesn't need a bank at all. BANK 3.0 shows that the gap between customers and financial services players is rapidly widening, leaving massive opportunities for new, non-bank competitors to totally disrupt the industry. "On the Web and on Mobile, the customer isn't king—he's dictator. Highly impatient, skeptical, cynical. Brett King understands deeply what drives this new hard-nosed customer. Banking professionals would do well to heed his advice." —Gerry McGovern, author of Killer Web Content
