Yes this is more definitely a scam attempt, trying to trick people into thinking they are investing into the coin from Facebook. They use a different URL than the official project, with a similar website. Real Libra project URL is https://libra.org/ and not https://libraproject.io
Thank you so much . Because of these scammers , nowadays bounty hunters and bounty managers are not getting any good project. When I see this type of fake thread I get angry on myself .
