Cryptocurrencies are often associated with right-wing political movements, or even with the alt-right. They are the preserve of libertarians and fans of Ayn Rand and Friedrich Hayek. With their promotion of anonymity and individualism, there-s no doubt that they seamlessly slot into the prevailing anti-State ideology. But in this book Mark Alizart argues that the significance of cryptocurrencies goes well beyond cryptoanarchism. In so far as they allow us -to appropriate collectively the means of monetary production-, to paraphrase Marx, and to replace -the government of persons by the administration of things-, as Engels advocated, they form the basis for a political regime that begins to look like a communism which has at last come to fruition - a cryptocommunism.
