Most congress members did not inquire deeply about Libra. They instead delved into smearing Facebook and its credibility.
They should have delved deeper into Libra, but this is what congressional hearings always amount to, ie, political posturing and attacks. On the other hand, I think facebook deserves some scrutiny about their privacy policies. A hearing about their crap stable coin just isn't the right place for it, tho. Our congresss just loves to do things like this. Always has, always will.
I am as indifferent to the fate of Libra as one can be. The world and future fate of crypto won't be affected either way if it never gets released and if it does, I have a feeling that there won't be many people who are enthusiastic about owning or using it. Are there that many people passionate about stable coins? Absolutely not. Facebook just wants another profitable thing, and they want to cash in on the crypto craze.
What worries me about Libra and the attention its getting from congress is that lawmakers might set a precedent here if they make a ruling on it. I am not *too* worried, but it is a possibility that any ruling could affect bitcoin and other cryptos, at least in the states.
