In the next decade Bitcoin will have passed through adolescence and reached adulthood. This book tells the fascinating journey of Bitcoin and why it could be the best investment opportunity of your life. You'll learn about Bitcoin's role in the history of money and why it's considered "good money" by many financial advisors, including the author, who has spent a decade and a half in the investment business. Bitcoin's value has grown exponentially over multiple boom and bust cycles spanning more than a decade. If Bitcoin reaches its potential, its value could rise by ten or even 100 times its current price. Bitcoin, like Alibaba, Amazon, Apple, Facebook, Google, Netflix, Microsoft, and Tencent, relies on the network effect (how many others are using it). But the market for money is much greater than the combined market values of the Internet giants.This book will help you understand why Bitcoin is the world's solution for the problem of money, the role of money in our economy, the current state of debt, and the particular intricacies of Bitcoin.
Some experts say that cryptocurrencies and blockchains are just a scam; others say they're "the most important invention since the internet." It's hard to tell who's right. Authored by Product Managers from Google, Microsoft, and Facebook, Bubble or Revolution cuts through the hype to offer a balanced, comprehensive, and accessible analysis of blockchains and cryptocurrencies. You'll learn the core concepts of these technologies and understand their strengths and weaknesses from real-world case studies; dive deep into their technical, economic, political, and legal complexities; and gain insights about their future from exclusive interviews with dozens of tech industry leaders. No coding or math needed! Are cryptocurrencies and blockchains a bubble or a revolution? We'll help you decide for yourself.

From the award-winning author of Sandworm comes the propulsive story of a new breed of investigators who have cracked the Bitcoin blockchain, exposing once-anonymous realms of money, drugs, and violence. “I love the book… It reads like a thriller… These stories are amazing.” (Michael Lewis) Over the last decade, a single innovation has massively fueled digital black markets: cryptocurrency. Crime lords inhabiting lawless corners of the internet have operated more freely—whether in drug dealing, money laundering, or human trafficking—than their analog counterparts could have ever dreamed of. By transacting not in dollars or pounds but in currencies with anonymous ledgers, overseen by no government, beholden to no bankers, these black marketeers have sought to rob law enforcement of their chief method of cracking down on illicit finance: following the money. But what if the centerpiece of this dark economy held a secret, fatal flaw? What if their currency wasn’t so cryptic after all? An investigator using the right mixture of technical wizardry, financial forensics, and old-fashioned persistence could uncover an entire world of wrongdoing. Tracers in the Dark is a story of crime and pursuit unlike any other. With unprecedented access to the major players in federal law enforcement and private industry, veteran cybersecurity reporter Andy Greenberg tells an astonishing saga of criminal empires built and destroyed. He introduces an IRS agent with a defiant streak, a Bitcoin-tracing Danish entrepreneur, and a colorful ensemble of hardboiled agents and prosecutors as they delve deep into the crypto-underworld. The result is a thrilling, globe-spanning story of dirty cops, drug bazaars, trafficking rings, and the biggest takedown of an online narcotics market in the history of the Internet. Utterly of our time, Tracers in the Dark is a cat-and-mouse story and a tale of a technological one-upmanship. Filled with canny maneuvering and shocking twists, it answers a provocative question: How would some of the world’s most brazen criminals behave if they were sure they could never get caught?
A straightforward, practical guide to the newest frontier in investment strategy—crypto—from #1 New York Times bestselling author and personal finance expert Ric Edelman. Blockchain and bitcoin are here to stay—and as the Bank of England stated, this new technology could “transform the global financial system.” No wonder PWC says blockchain technology will add $2 trillion to the world’s $80 trillion economy by 2030. Indeed, blockchain technology and the digital assets it makes possible are revolutionary, the most profound innovation for commerce since the invention of the internet. And yet, the average investor—and the investment advisors who manage two-thirds of all their money—aren’t aware of all this, or of the incredible investment opportunities now available. Fortunately, Ric Edelman, one of the most influential experts in the financial field, shows investors how they can engage and thrive in today’s new investment marketplace. Featuring the prophetic insights you’d expect from one of most acclaimed financial advisors, The Truth About Crypto is fun to read and easy to understand—and most importantly gives readers the sound, practical advice we all need to succeed with this new asset class. Best of all, Edelman shows how blockchain works, the difference between digital currency and digital assets, and a comprehensive look at every aspect of the field. This book is a must-read guide if you want to achieve investment success today.
