Wu said that lawyer Liu Yang wrote that in the future, China may implement a licensing system for certain virtual currency businesses, such as the exchange of legal currency and virtual currency; relevant ministries are standardizing the judicial processes and judicial handling of virtual currencies; considering the current judicial situation, it is possible to license relevant departments to engage in the exchange of virtual currency for legal currency, and it is very likely to be one-way rather than free exchange; however, it is difficult to loosen the buying and selling of virtual currencies, and the issuance of coins and mining cannot be relaxed at this stage.
