"No, it's a p2p digital currency.".

Yes, but from a technical standpoint bitcoin displays traits associated with social networking. It's definitely not a easy-to-use social network (for most people), that's for sure. The only difference is, any identifying features of the user are usually replaced with random strings of numbers and letters.

-connection between two users
-communication between two users
-sharing of information between two users
-forming of relationships between two users

On the other hand, definitions of social media usually describe a service that enables the ability for a user to create and share content, or to participate in the act of social networking.

From what I understand, bitcoin doesn't support or really have a use for user generated content sharing and uploading. It's currency after all, not Instagram. 

But it's currency that let's you talk to another person with the only requirement being they are using the same software.


Of the three options, I think bitcoin is a social network.
