I am not sure why everyone is so enthused about a giant corporation making a massive bid on a proprietary crypto currency. The whole purpose of crypto was to decentralize currency and remove authoritative and centralised controlling bodies such as multi-national corporations. Also some say this is good for bitcoin because it will bring attention to crypto currencies. But Facebook has a track record of bungling new products, ie the Facebook Phone, and would abandon this whole endeavour like a hot steaming pile of turd if ever investors became worried that it was underperforming, bringing too much controversy, threatening other investments, etc. And after its likely failure, it will leave all those people who were newly introduced to crypto though this rollout the perception of crypto as being a failure.
