Virtual currencies, in their broadest sense, encompass both cryptocurrencies and non-cryptocurrencies. This article focuses specifically on cryptocurrencies like Bitcoin—representing the narrow definition of virtual currencies. Among numerous types, Bitcoin remains the earliest and most iconic example, created in 2009 by an anonymous entity known as Satoshi Nakamoto as a peer-to-peer decentralized financial system. Virtual currencies are typically issued by individuals, companies, or organizations.
How Virtual Currencies Operate
Transactions involving virtual currencies are recorded on a blockchain—a distributed ledger structured as a chain of cryptographic blocks. This technology ensures:
- Immutability: Transactions cannot be altered retroactively.
- Security: Cryptographic protocols prevent forgery.
Users interact with virtual currencies through:
- Accounts: Track transaction states on the decentralized network.
- Wallets: Store private keys to access funds.
Given that blockchains facilitate value transfer, securing accounts, wallets, and transactions is critical. Wallet types vary by private-key generation:
- Hardware wallets
- Software wallets
- Custodial wallets
- Threshold wallets
Legal Status and Property Attributes
While many jurisdictions, including China, do not recognize virtual currencies as legal tender, they acknowledge their property-like attributes, treating them as unique digital commodities. Courts have upheld this view, ruling that virtual currencies qualify as protected assets under law. However, some legal scholars argue they should be classified as computer system data—a perspective reflected in certain criminal rulings.

Regulatory Landscape
Initially, regulators adopted a观望 (wait-and-see) approach toward virtual currencies before tightening policies to curb speculative trading. Restrictions aim to mitigate risks—not outlaw ownership—highlighting concerns over market volatility.
Dual Nature: Property vs. Data
Like a black sedan possessing both color and vehicle traits, virtual currencies exhibit:
- Property characteristics (economic value, transferability).
- Data attributes (digital representation, code-based structure).
Dismissing either aspect is flawed; a balanced recognition of both dimensions is essential for comprehensive understanding and regulation.
