Questions & Answers

Q: What is Libra and how is it different from other cryptocurrencies?

Q: How does Libra's record-keeping model differ from Bitcoin?

The regulatory environment for Libra is uncertain, with many governments expressing concerns about its impact on their monetary policies. The House Financial Services Committee has called for a moratorium on Libra's development, and France's finance minister has stated that Libra can't and must not happen.
