Facebook have attempted to create facebook money before but it ended up as a failure and using the same idea but in the form of a digital money powered up by blockchain technology; facebook once again is thinking to create a cryptocurrency to suit their purposes but one thing is clear and that it will take a very long time before they can realize their idea and at the same time there will be no ICO for that crypto.
Would be off to see those giftcards at the gas station for $20 worth of Facebook coin which can be traded for Bitcoin on an exchange.
