This thesis addresses the widespread questions asked of Bitcoin. Cryptocurrencies - decentralized ledgers of peer to peer transactions – have taken the world by storm, with Bitcoin leading the way by means of being the original, most valuable, and most popular. Despite this widespread use, skepticism remains as to what Bitcoin is and whether it counts as money. I first defend the framework that I use for understanding Social Objects, Searle’s X counts as Y in C formula, as money is undoubtedly a social object. I then argue that Smit et al.’s account of money, while useful, mistakenly identifies an essential characteristic of money, the relative ratio scale, as a feature. I therefore present an alternative account of money. I then explain why the most commonly held account of Bitcoin, the chain Definition fails, and why Bitcoin being a fictional substance is not a problem for Bitcoin being money. I then demonstrate Bitcoin’s compatibility with my alternative account, and from this conclude that Bitcoin is Money.
