There's no need to create a cryptocurrency around this tired old idea. In fact, doing so makes the entire system worse for users. The last thing Joe or Jane Sixpack wants to do is manage cryptographic keys. S/he's going to keep this stuff on a centralized account anyway, so why not build that product instead? If Facebook sees a market for a bank account denominated as a floating basket of currencies, they can do that purely with centralized ledgers. I just don't see the point of this given the deluge of similar projects already and the poor match to Facebook's mostly low technical literacy clientele.
