David Birch 
Currency Cold War: Cash and Cryptography, Hash Rates and Hegemony [PDF ebook] 

Money is changing and this may mean a new world order. David Birch sets out the economic and technological imperatives concerning digital money, and discusses its potential impact. Tensions will inevitably arise: between old and new, between public and private, and, most importantly, between East and West. This book contributes to the debate that we must have to shape the International Monetary and Financial System of the near future.
