Digital currencies, including potential central bank digital currencies (CBDC), have generated a lot of interest over the past decade, since the emergence of Bitcoin. The interest has only grown in recent months because of a desire for contactless payment methods, stemming from the coronavirus pandemic.

We show that this distinction is problematic because Bitcoin and many other digital currencies satisfy both definitions.
