We begin by explaining the idea that digital currencies are an emerging market, and develop some of the benefits they possess over the use of fiat currencies. We then move on to argue that there is a growing discussion amongst states of whether to adopt their own form of digital currency, and how states with hostile reputations towards foreign investors will use these digital currencies as a new way to attract foreign investment, but also to limit their sovereign immunity. We conclude by showing that these emerging technologies will provide investors with additional tools to resort to investor-state arbitration.
