Welcome to the community! The Libra project is currently in pre-launch/test mode. Once Libra is launched (and at this time, we do not have a confirmed launch date), you will be able to buy Libra through exchanges that list it, or through applications that have been built to let you purchase Libra through their payment systems. In the meantime, you should be aware that a few websites have emerged claiming to represent the Libra Association. Trust only the official domain (libra.org) and our developer website (developers.libra.org).
