One of the things I have come to understand is, when a good platform or organisation is building something good related to crypto it will be in the waves, it will be around every corner of the crypto space and so on, now about what Facebook is working on, after the issue with Libra it seems people moved their attention from them thus no one is even realising they are still working on something. To be frank I am just getting to know about this, that is to say, many crypto channels are not even paying attention to it, therefore I can't say it is solid or not, until they start showcasing what they are working on.
Lastly, owing to what happened to Libra people might still be skeptical in anything relating to Facebook and so on, nevertheless until they launch then we will know if there is a chance of it having unique attributes or not. This further goes to show that, crypto and everything relating to it is becoming hard to ignore by top organisations.
