Recently, the "14th China CFO Conference and 2018 China CFO Annual Persons Awards Ceremony" was held in Beijing. Yang Zhiguo, CEO of Lixin Certified Public Accountants, said that the encryption assets and cryptocurrencies formed by the blockchain became a form of wealth. However, how to carry out accounting confirmation, measurement and presentation is inconsistent. Whether the cryptocurrency is cash, financial assets, inventory, or intangible assets, different accounting treatments have a great impact on the enterprise. If the cryptocurrency private key is personally remembered by the management or stored in the personal e-wallet, how to judge the public property belonging to the enterprise also constitutes an audit problem.
