I think since there is a lot of Facebook users, the coin will be bought so many people. Investors will also be interested in investing in that coin. Users of Facebook do not only include regular people but also high level individuals or corporation that can make the coin a success and popular.
The large user database that Facebook has on their social media database is quite huge for them to record success in their projects. This coin in question will not even be for regular people on Facebook, because most regular people on Facebook use the platform for free and have no need for it, but it will be for large institutions that are using Facebook to get their product across to the world out there.
These are the people presently making Facebook have the money it has recorded and since there is a transaction system going on within Facebook system, then the coin will very useful to the people that are concerned.
