On June 19th, ShapeShift CEO Erik Voorhees said on Twitter today that Libra is not a pure cryptocurrency. Don't think that Libra is private and borderless; regulators can block transactions, and users don't want to be completely free finance. A little more on other cryptocurrencies. Any cryptocurrency supported by fiat currency will be at a disadvantage to the "real" cryptocurrency such as BTC. In the short or medium term, this relative stability by statutory or bond support will allow Libra to gain significant market share. Since Libra is only a “partial” cryptocurrency, the challenge of compliance issues is relatively small, and the resources that Facebook has accumulated may be helpful. We need to look forward to the birth of Libra in a dialectical way.
