The growing global interest in digital assets has sparked renewed attention on the legal classification of cryptocurrencies. As blockchain technology evolves and adoption accelerates across industries, courts in common law jurisdictions have begun to address whether digital assets qualify as property under existing legal frameworks. These landmark rulings offer valuable insights into how cryptocurrencies may be treated in legal contexts—ranging from ownership and trust arrangements to insolvency and enforcement remedies.
While judicial decisions often hinge on specific facts, they collectively suggest a trend toward recognizing certain types of crypto assets as legitimate forms of property. However, this recognition is not universal or automatic. To fully grasp the implications, it's essential to understand the different classifications of crypto assets and how various legal systems apply established property principles.
Classifying Cryptocurrencies and Digital Assets
Though often used interchangeably, "cryptocurrency" refers only to one category within the broader spectrum of crypto assets. These digital representations of value can be categorized based on function, issuance model, and transferability.
Functional Classification
A widely adopted framework—developed by the UK’s Cryptoassets Taskforce (a joint effort between the Bank of England, HM Treasury, and the Financial Conduct Authority)—divides crypto assets into three primary types:
- Payment Tokens – Commonly known as cryptocurrencies (e.g., Bitcoin, Ethereum), these serve as a medium of exchange.
- Security Tokens – Designed to function like traditional financial securities, representing ownership or entitlement to profits, dividends, or interest.
- Utility Tokens – Grant holders access to a product or service within a specific platform or ecosystem.
Additional subcategories include platform tokens, which enable interaction with decentralized applications (dApps), and asset-backed tokens, which are pegged to real-world assets such as gold or real estate.
Issuance Model: Public vs. Private
Crypto assets can also be classified by who issues them. Most current tokens are privately issued by companies or decentralized communities. However, central banks worldwide are exploring central bank digital currencies (CBDCs), which would represent state-issued digital money with full legal tender status.
Transferability: Fungible vs. Non-Fungible
Another key distinction lies in transferability:
- Fungible tokens (like Bitcoin) are interchangeable and divisible.
- Non-fungible tokens (NFTs) and identity or certification tokens are unique and typically non-transferable. These may represent digital identity, licenses, or credentials.
As the technology matures, classification systems will continue to evolve—reflecting both innovation and regulatory needs.
Global Legal Perspectives on Crypto as Property
Several common law jurisdictions have addressed whether crypto assets qualify as legal property, often referencing the classic four-part test from National Provincial Bank v Ainsworth [1965] AC 1175:
For something to be considered property, it must be:
- Capable of precise definition
- Identifiable by third parties
- Capable of being transferred or possessed by others
- Possessing some degree of permanence or stability
Let’s examine how courts in key jurisdictions have applied this test.
Singapore: B2C2 Ltd v Quoine Pte Ltd
In B2C2 Ltd v Quoine Pte Ltd [2019] SGHC(I) 03, the Singapore International Commercial Court considered whether Bitcoin and Ethereum could be held in trust. The case involved erroneous trades executed on a crypto exchange due to a system glitch, resulting in significant gains for one party.
The court assumed—without definitive ruling—that cryptocurrencies could constitute property because they met the Ainsworth criteria. Notably, the judge found that crypto assets were definable, identifiable, transferable, and stable enough to qualify as property.
On appeal, the higher court avoided ruling on property status, instead dismissing the trust claim due to lack of intention to create a trust. Still, the judges noted that “there is much to be said for the view that cryptocurrency can be treated as property.”

United Kingdom: AA v Persons Unknown
In AA v Persons Unknown [2019] EWHC 3556 (Comm), an English insurer paid a Bitcoin ransom to decrypt a client’s hacked system. The insurer sought a proprietary injunction to trace and recover the funds.
The court relied on the UK Jurisdiction Taskforce’s Legal Statement on Cryptoassets and Smart Contracts, which affirmed that crypto assets generally satisfy the Ainsworth test and can be treated as property for legal purposes.
Justice Bryan accepted that Bitcoin met all four criteria and granted the injunction, marking a pivotal moment in recognizing crypto as enforceable property in English law—even if decided in an ex parte setting.
New Zealand: Ruscoe v Cryptopia Ltd
Following a major hack that wiped out NZ$30 million in customer funds, the liquidators of exchange Cryptopia sought clarity on the status of remaining assets worth NZ$170 million.
The High Court ruled that cryptocurrency held by the exchange could be held on trust for users. It emphasized that crypto is more than just data—it enables exclusive control and secure transfer, distinguishing it from mere information.
This decision reinforced the idea that fungible, transferable crypto assets can function as traditional property in insolvency proceedings.
Why Context Matters: Legal Status Depends on Use Case
It’s crucial to recognize that no single ruling establishes a blanket classification for all digital assets.
- In Singapore, the property status remains technically unresolved.
- In the UK, recognition was granted specifically for the purpose of issuing an injunction—not a comprehensive declaration.
- All cases focused only on specific types of crypto (e.g., Bitcoin, Ethereum), not NFTs or non-transferable tokens.
Moreover, something may qualify as property for one legal purpose (e.g., recovery) but not another (e.g., taxation or inheritance). Statutes can also override common law interpretations.

Implications of Treating Crypto as Property
If classified as property, crypto assets gain significant legal standing:
- Enforceable against third parties: Ownership rights are not just personal—they bind the world.
- Priority in insolvency: Holders may recover assets ahead of unsecured creditors.
- Trust structures become viable: Enables custodial arrangements and estate planning.
- Proprietary remedies available: Including tracing, restitution, and injunctions.
- Collateralization possible: Crypto can back loans through security interests like pledges—provided possession requirements are met.
Frequently Asked Questions (FAQ)
Q: Are all cryptocurrencies legally recognized as property?
A: No. Recognition depends on jurisdiction, asset type, and legal context. Most rulings apply only to fungible payment tokens like Bitcoin.
Q: Can I hold cryptocurrency in a trust?
A: In several jurisdictions—including the UK and New Zealand—courts have accepted that crypto can be held in trust if it meets traditional property criteria.
Q: What happens to my crypto if an exchange goes bankrupt?
A: If the crypto is deemed your property (not the exchange’s), you may have priority claims during liquidation. Otherwise, you're treated as an unsecured creditor.
Q: Do NFTs qualify as legal property?
A: Potentially—but since NFTs may fail the "transferability" or "third-party identifiability" tests, their status is less certain than fungible tokens.
Q: How does Hong Kong view crypto assets legally?
A: While not bound by overseas rulings, Hong Kong courts may find them persuasive. Local legislation is evolving, especially with increased interest in virtual asset trading platforms.
Q: Should I seek legal advice before investing in crypto?
A: Absolutely. Due to rapid technological change and uncertain regulation, tailored legal guidance is essential for compliance and risk management.

Final Thoughts
The trajectory is clear: courts in major common law jurisdictions are increasingly willing to treat certain crypto assets—particularly fungible, transferable ones—as property. This shift supports greater legal certainty for investors, businesses, and financial institutions operating in the digital economy.
However, classification remains fact-specific and jurisdiction-dependent. As new token models emerge—from DeFi governance tokens to AI-powered digital collectibles—the law must continually adapt.
For now, stakeholders should proceed with caution, understanding that while precedent is building, definitive legal frameworks are still in development. When navigating ownership, inheritance, or dispute resolution involving digital assets, independent legal counsel is indispensable.
As blockchain reshapes finance and ownership models, one thing is certain: the conversation around crypto’s legal identity is just beginning.
