Facebook coin (Libra) was never going to compete with bitcoin because it's a stable coin. It will take much more than just this to unsit bitcoin
Indeed, a stable coin can't compete to a coin that can move up high easily and beside from being a stable coin Facebook coin is centralized and right now they are facing a big pressure from the US Government so investors will have doubt now if its continues to become a problem. Adoption with cryptocurrency is good, more companies will go and compete with each other but they can't create a threat to bitcoin because its a strong coin and many investors will backed up bitcoin.
Right, I think that Libra is not any danger to Bitcoin. This is something completely different, but I think that (maybe) thanks to Libra, some of the toppest brands like Visa, PayPal or Mastercard etc. will support the platforms where you can buy Bitcoin like for example
buycoinnow. That would be great if Libra were the beginning of a "buying revolution" in the cryptocurrency world
