Not very impressed with it. I wouldn't even call it an alt coin. They are just some centralized coin. I don't see much difference between Libra payment system and Paypal. The only main difference is that facebook will be using the blockchain technology. If I am not wrong, even the price will be 1:1 in terms of USD. Was never a huge fan of centralized coin. Though this might help people to better understand the blockchain technology. So yeah, we do have some good sides over here.
