Apart from the ambiguity on the OS running the demo app in the video: this project really intrigues me. I guess I'm exactly the kind of people they're trying to market this: I don't have a clue about how all this cryptocurrency thing works, and I've never had the time to even bother trying to understand it (the fact that it seems a bit unpractical to manage, too, didn't help). If this makes it easy and straightforward, I'm definitely all ears.
