At the 6th World Internet Conference, the Chinese Academy of Engineering academician He Hezhen said on the issue of cryptocurrency: technology has never been a problem, and encryption of digital currency is no problem. He believes that technology is not everything. Encrypted digital currency cannot be liberalized. As the currency needs to be monitored and guided by the central bank, the US financial management department does not support Libra. The EU has also explicitly opposed Libra. Money involves financial order and social stability. It is not something that a company can do independently. The cryptocurrency needs to be developed under the supervision of the government.
