Bitcoins and other cryptocurrencies as property

ABSTRACT The hype over bitcoins and other cryptocurrencies has been compared to the tulip mania in seventeenth-century Netherlands. As they have gained popularity, the law has approached the subject warily, mostly from a regulatory perspective. However, there has been no comprehensive consideration of the fundamental nature of a cryptocurrency owner’s private law relation to his cryptocurrencies. Whether or not cryptocurrencies achieve mainstream adoption, this question will inevitably have to be addressed. This paper considers if bitcoins and other cryptocurrencies might be recognised as the subject of property rights by Commonwealth courts and if so, what such rights ought to entail. It begins with a consideration of the controversial question of the scope of the law of property before considering bitcoin’s place within it. It suggests that the common law adopts a more expansive view of property than civilian systems and that it is thus able to accommodate bitcoins and other cryptocurrencies within its law of property. However, owing to their unusual nature, legal rights to them must take on a unique and unorthodox form. This paper also addresses the particular challenges to the law that are posed by the code underlying bitcoin.

Legal risks of owning cryptocurrencies

Cryptocurrencies like Bitcoin have matured from being associated exclusively with techies and radicals to being considered by central banks as a technology to implement digital money. Cryptocurrencies exist only in digital form and can be transferred completely between digital addresses. This is both unlike conventional electronic money as understood by laypersons which acts as a debt claim on a deposit with a trusted financial institution such as a private bank and unlike conventional corporeal money which may be physically possessed. This means that any legal rights associated with holding cryptocurrencies must be different despite it being remaining open to interpretation. In this chapter, we look at the various treatments of money in the legal sense and discuss the risks associated with each by drawing on real life examples. We conclude that fraud through hacking could potentially pose a problem to widespread adoption of cryptocurrencies as the absence of recourse against a third party such as a bank concentrates risk in holders of cryptocurrencies. Users should thus exercise caution and understand the risks before investing in cryptocurrencies. This warning requires emphasis as many parties misapprehend the cryptography within the technology as protecting them from such fraud when in fact it does no such thing.
