and from those facebook users that will initially use libra coin, these users later on will learn the difference between libra and bitcoin, they might eventually go for the latter. their privacy is at stake with libra. and i dont think most people will prefer to have open lives to this platform!
is it okay for you to receive notifications inviting you to some event that you have absolutely no idea and no interest of! or getting a message from nobody that they know you are in town and offering you to a spa for huge discount because you are a libra user? i think this will turn into a creepy app sneaking on your private lives. if it will ever come to life!
