When Nobel laureate Friedrich August von Hayek called for the end of the state’s money monopoly and a free competition of currencies in 1976, his concept was not taken very seriously. Today, the denationalization of money is in full swing. Digital currencies like Bitcoin operate without banks and without state regulation. This book describes the concept of decentralized, non-state money in an easily understandable and illustrative manner. The author examines the payment system Bitcoin from the perspective of the Austrian School of Economics. Thinkers like Hayek, Ludwig von Mises, and Murray Rothbard criticize the harmful effects of monetary socialism and advocate for a free market economy without state intervention. With Bitcoin, their demand for free market money becomes a reality. And the underlying blockchain technology of Bitcoin can do even more!.
