Is cryptocurrency "property"?

A shorter than usual blogpost today:

Yes.

The conclusion that was expressed was that a crypto asset might not be a thing in action on a narrow definition of that term, but that does not mean that it cannot be treated as property. Essentially, and for the reasons identified in that legal statement, I consider that a crypto asset such as Bitcoin are property. They meet the four criteria set out in Lord Wilberforce's classic definition of property in National Provincial Bank v Ainsworth [1965] 1 AC 1175 as being definable, identifiable by third parties, capable in their nature of assumption by third parties, and having some degree of permanence. That too, was the conclusion of the Singapore International Commercial Court in B2C2 Limited v Quoine PTC Limited [2019] SGHC (I) 03 [142].

At least, for some purposes:

... [F]or the reasons I have given, as elaborated upon in the Legal Statement which I gratefully as what I consider to be an accurate statement as to the position under English law, I am satisfied for the purpose of granting an interim injunction in the form of an interim proprietary injunction that crypto currencies are a form of property capable of being the subject of a proprietary injunction.

Does decoded.legal take Bitcoin or other cryptocurrency for payment? Not yet.
