"Inflation, depressed economies, debased currencies... these are just a few of the problems centralized banking has caused throughout history. Bitcoin, a digital currency created with the ambition to shift control away from change-prone governments, has the potential to bring an end to those problems once and for all. It's time to find out how it can help you. Grokking Bitcoin explains why Bitcoin's supporters trust it so deeply, and why you can too. This approachable book will introduce you to Bitcoin's groundbreaking technology, which is the key to this world-changing system. This illustrated, easy-to-read guide prepares you for a new way of thinking with easy-to-follow diagrams and exercises. You'll discover how Bitcoin mining works, how to accept Bitcoin, how to participate in the Bitcoin network, and how to set up a digital wallet." - Back cover

Zusammenfassung
Die Finanzkrise von 2007/2008 gilt weithin als die schwerwiegendste globale Finanzkrise seit der Großen Depression. Während Akteure der etablierten Institutionen des Finanzsystems seinerzeit versucht haben, durch hektische Eingriffe den Kollaps des Finanzsystems abzuwenden, haben verschiedenen Protestbewegungen begonnen, über Alternativen nachzudenken. Dieser Beitrag befasst sich mit einem aktivistischen Alternativgeldexperiment, das uns seitdem besonders beschäftigt hat: Bitcoin. Dabei wird untersucht, wie sich Bitcoin seit seinen Anfängen entwickelt hat, welche Fragen es aufgeworfen hat und welche Implikationen sich aus den Erfahrungen mit diesem Experiment ergeben.

Criptocurrencies are popular convertible virtual currencies, as they use security mechanisms such as cryptography for creating units of the currency and controlling the transaction. Th e main property of criptocurrencies is that they provide anonymity for the transaction, as they work based on Blockchain technology. Bitcoin is one of the most important criptocurrencies on the market. Whereas we like it or not, it seems that Bitcoin has become a powerful payment instrument, but also a payment system. Th e national Governments face now a new challenge: the necessity of regulating Bitcoin. But Bitcoin is incompatible with any kind of centralized control. We can only imagine that eff ective regulations can exist only through worldwide cooperation: "Bitcoin and other virtual currencies are present and growing in major economies, supporting the call for increased global cooperation"21. Th is will be probably an expensive and complex process.

AbstractPeriodically collapsing rational bubbles model speculative demand in asset markets. The price and quantity of bitcoin are integrated of different orders, which is evidence of a bubble. Cointegration tests that allow for the potential presence of such bubbles with alternative proxies for fundamentals cannot reject a bubble in bitcoin.

"A broad introduction to bitcoin--ideal for non-tech users, investors, and business executives; technical foundations of bitcoin and cryptographic currencies for developers, engineers, and software and systems architects; details of the bitcoin decentralized network, peer-to-peer architecture, transaction lifecycle, and security principles; offshoots of the bitcoin and blockchain inventions, including alternative chains, currencies, and applications; user stories, elegant analogies, examples, and code snippets illustrating key technical concepts"--Page [4] of cover

Klappentext: The definitive guide to the game-theoretic and probabilistic underpinning for Bitcoin's security model. The book begins with an overview of probability and game theory. Nakamoto Consensus is discussed in both practical and theoretical terms. This volume: Describes attacks and exploits with mathematical justifications, including selfish mining. Identifies common assumptions such as the Market Fragility Hypothesis, establishing a framework for analyzing incentives to attack. Outlines the block reward schedule and economics of ASIC mining. Discusses how adoption by institutions would fundamentally change the security model. Analyzes incentives for double-spend and sabotage attacks via stock-flow models. Overviews coalitional game theory with applications to majority takeover attacks Presents Nash bargaining with application to unregulated environments This book is intended for students or researchers wanting to engage in a serious conversation about the future viability of Bitcoin as a decentralized, censorship-resistant, peer-to-peer electronic cash system.

The proliferation of technology emphasized new forms of payment. During the last years, current literature highlighted the role of virtual currency, the channels of payment through digital coins and the importance of assimilation of such platforms. Bitcoin or BTC is known as a digital coin, issued for the first time in 2009 and based on a peer to peer system. The difference from other forms of payment is that BTC is not controlled by any institution or central authority. BTC transactions have grown rapidly, "asking" for regulation measures or legal approval of governments. Although BTC has become very popular, the market is poor and unfortunately of no confidence. There is a lack of regulation which can determine a number of risks associated with criminal financing activities. However, the legal status of Bitcoin is present in many European countries like Belgium, Bulgaria, Denmark, Finland, Germany, Lithuania, Norway, Poland, Slovenia, Switzerland or Turkey. Also, this type of currency has experienced a rapid evolution among coffee shops and restaurants.

The E.U.'s new virtual currency regulations will endanger privacy and trigger an exodus of tech talent from Europe, hobbling its role in the future of finance.
