Blockchain technology has rapidly evolved from a niche cryptographic innovation into a transformative force across industries. At its core, blockchain emerged with the advent of Bitcoin—a decentralized digital currency system introduced in 2008 by an individual or group under the pseudonym Satoshi Nakamoto. The publication of the whitepaper titled Bitcoin: A Peer-to-Peer Electronic Cash System and the subsequent launch of the Bitcoin network’s genesis block in January 2009 marked the birth of the first functional blockchain.
Bitcoin operates on principles such as decentralization, immutability, traceability, and distributed consensus, allowing it to function without central oversight. Over time, blockchain has expanded beyond cryptocurrencies into areas like financial services, supply chain management, artificial intelligence, and the Internet of Things (IoT). However, as virtual currencies gain traction, so do legal and regulatory concerns—especially regarding their use in financial transactions, investment vehicles, and technological platforms.
This article explores the intersection of blockchain technology and virtual currency through the lens of legal frameworks, judicial precedents, and compliance strategies. We examine key concepts, analyze relevant regulations in China, identify common legal risks, and provide actionable recommendations for investors and service providers.
What Is Blockchain-Based Virtual Currency?
Blockchain is a decentralized and trustless system for maintaining a secure, transparent, and tamper-proof digital ledger. It records transactions across multiple nodes in a way that ensures data integrity and prevents unauthorized alterations.
The first major application of blockchain—often referred to as Blockchain 1.0—is virtual currency. Bitcoin remains the most prominent example.
Key Characteristics of Bitcoin
- Decentralization: No single entity controls the network; all participants (nodes) maintain copies of the ledger.
- Limited Supply: The total number of Bitcoins is capped at 21 million, ensuring scarcity.
- No Central Issuance: Unlike fiat money issued by central banks, Bitcoin is generated through computational mining.
- Pseudonymity: Users transact via public addresses linked to cryptographic keys. While not fully anonymous, identities are obscured.
- High Security: Transactions are time-stamped and cryptographically verified. Altering historical data would require controlling over 50% of the network’s computing power.
- Borderless Transactions: Bitcoin can be transferred globally without geographic restrictions.
Despite these technical advantages, Bitcoin does not have legal tender status in any jurisdiction, including China.
Regulatory Landscape in China
Due to the potential misuse of virtual currencies in money laundering, fraud, illegal fundraising, and other financial crimes, Chinese authorities have issued several regulatory documents to clarify the legal boundaries:
- Notice on Preventing Bitcoin Risks (2013)
- Announcement on Preventing Risks of Token Issuance Financing (2017)
- Regulations on Blockchain Information Services (2019)
- Risk Warning on Illegal Fundraising Using “Virtual Currency” and “Blockchain”
These policies establish critical guidelines:
- Bitcoin is not legal tender. It is classified as a virtual commodity, not currency. It cannot be used for everyday payments or price denomination.
- Financial institutions are prohibited from offering services related to Bitcoin trading, custody, or insurance.
- Token issuance financing (e.g., ICOs) is illegal. Raising funds by issuing tokens is deemed unauthorized public financing and may constitute securities violations or fraud.
- Cryptocurrency exchanges cannot facilitate conversions between fiat and virtual currencies or act as market makers.
These rules reflect a cautious approach aimed at protecting financial stability while acknowledging the underlying value of blockchain innovation.

Legal Risks in Practice: Insights from Judicial Cases
Risk 1: Invalid Contracts for Buying/Selling Virtual Currencies
Case: Zhou Jie v. Huang Jun (2019 Hunan 01 Min Zhong No. 6246)
Huang purchased "Bangbei" and "Xilian" tokens from Zhou but later lost access to his account and sought a refund. Courts ruled the transaction invalid because the tokens were unregulated and served no legitimate economic purpose.
Takeaway: Only blockchain-based assets with verifiable scarcity and decentralized issuance—like Bitcoin—may be recognized as virtual property. Tokens issued privately without oversight are often deemed illegal financial instruments.
Risk 2: Losses from Entrusting Investments in Mining Projects
Case: Wu Xingzhi v. Shuang Yuxuan (2018 Jiangsu 02 Min Zhong No. 3731)
Wu invested in a "virtual mining machine" project promising returns in "Tick Coin." After receiving minimal payouts, he demanded repayment of the principal. The court ordered the return of remaining funds due to lack of proof of actual investment.
Lesson: Entrusting funds for speculative crypto ventures carries high risk. Courts may side with investors only when clear evidence of misuse exists.
Risk 3: Legality of Bitcoin Mining Equipment Sales
Case: Chen Guogui v. Ebang International (2018 Zhejiang 01 Min Zhong No. 10053)
Chen bought Bitcoin mining rigs but later refused delivery. The court upheld the contract’s validity, stating that mining hardware sales are legal unless specifically banned.
Implication: While mining operations face increasing scrutiny (especially due to energy consumption), the equipment itself remains lawful to buy and sell.
Risk 4: Bitcoin as an Object of Fraud
Case: Pei Siyuan Fraud Case (2016 Guangdong 19 Xing Zhong No. 573)
Pei created a fake trading platform, lured victims into sending Bitcoin, then disappeared. The court recognized Bitcoin as property subject to theft or fraud, citing its market value and transferability.
Significance: Virtual assets can be protected under criminal law if they possess economic value and are capable of being controlled.
Risk 5: Token Issuance Linked to Illegal Fundraising
Case: Ni Tingying – Illegal Deposit Absorption (2018 Zhejiang 07 Xing Zhong No. 33)
Ni promoted "Wanfubi" and "Libi" as high-return investments, collecting over 1.1 million RMB from the public. She was convicted of illegal absorption of public deposits.
Warning: Promising guaranteed returns on unregistered tokens violates China’s financial regulations.
Risk 6: Cryptocurrency-Based Pyramid Schemes
Case: Yan Guihua & Yang Tingran – Leadership in Pyramid Scheme (2019 Hunan 0922 Xing Chu No. 70)
Defendants launched "Yataifang Coin," requiring purchases for membership and rewarding recruitment. This structure met the legal definition of a pyramid scheme.
Red Flag: If income depends more on recruiting others than product value, it’s likely illegal.

Risk Mitigation Strategies
1. Understand the Nature of Virtual Assets
Investors should differentiate between genuine blockchain-based currencies like Bitcoin and speculative tokens lacking technical merit or regulatory approval. Be wary of projects promising unrealistic returns or using vague “blockchain” branding.
2. Secure Your Digital Wallets
Since access relies on private keys:
- Transfer coins off exchanges after purchase.
- Use hardware wallets for long-term storage.
- Back up encrypted key files in multiple secure locations.
3. Avoid Token Issuance Without Compliance
Launching an ICO or similar fundraising mechanism without authorization violates Chinese law. Even well-intentioned projects risk prosecution unless they follow strict regulatory procedures.
4. Platform Operators: Strengthen Compliance
Service providers should:
- Register under the Blockchain Information Service Regulations.
- Enforce user real-name authentication.
- Provide clear risk disclosures in user agreements.
- Invest in cybersecurity to prevent breaches.
In essence, while blockchain offers revolutionary potential, navigating its legal landscape requires caution. Like diamonds—valuable due to scarcity and consensus—Bitcoin derives worth from shared belief and technical resilience. But unlike regulated assets, virtual currencies operate in a gray zone where innovation meets enforcement.
For those entering this space, understanding both technology and law is essential—not just for profit, but for protection.
