Set in Tel Aviv's Bitcoin Embassy between 2017 and 2019, Community in a Crowd explores the everyday activities and social dynamics of Israeli Bitcoin enthusiasts. It examines how participants promoted Libertarian narratives and ritualized practices to challenge the moral authority of the 'centralized' political-economic order. Revisiting Bitcoin's popular association with radical individualism, the book contrasts the sprawling, impersonal crowds of online trading with the formation of an intimate, egalitarian community through in-person encounters. Advancing a new theoretical framework, it offers insights into contemporary mass movements grounded in techno-utopian visions of society and reconsiders how decentralized technologies foster both anonymity and solidarity.
