Facebook released its white paper on their crypto, Libra. So far I see as many negatives as positives. The biggest negatives are the investors - I do not trust them, and the fact that you must show a government ID in order to use it. I do not care for that. The positives include ease of use, possible widespread adoption, and it will be stable. Libra will possibly get more people involved in other crypto - the anonymous "wild west" versions. Overall, Libra is a draw - equally good and bad.
