Using digital currency to conduct e-book transactions to deliberately avoid the transaction records being traced to specific books is an illegal and potentially risky behavior that violates laws, regulations and regulatory requirements, and damages market order and copyright protection and other interests. Therefore, it should not be advocated or implemented. Although digital currency has a certain degree of anonymity, many countries and regions are constantly strengthening the supervision of digital currency transactions and cracking down on the use of digital currency for illegal financial activities, money laundering, tax evasion and infringement of intellectual property rights. Legal and compliant e-book transactions should follow the corresponding market rules and legal provisions and be conducted through formal payment channels to ensure the legality, security and traceability of transactions, and jointly maintain a healthy and orderly digital content market environment.
