I believe this coin is a lame attempt by Facebook to jump on the crypto currencies. Yes, even though the company recruited numerous expert researchers and a knowledgeable development team to work on this project, it will ultimately wind up either lagging behind true crypts or just failing altogether.
Any coin that is developed and controlled by a company will not be decentralized. Even if billions of Facebook users start using the coin, it will not have all the advantages of a decentralized cryptocurrency.
