Well i honestly think that it is highly overrated and over hyped, do we really need a coin to use on Facebook, Instagram or wahtsup, sure they are popular and it will think that it will be successful  at first because people know that facebook has already an wide established number of people, but people will realize that it will be kind of useless, i think that this is an attempt of make huge profit from the company and ride upon the idea of making a coin, but it will die out after a couple of months after its launch.
