The legal classification of Bitcoin remains a widely debated topic in academic literature. This issue touches upon numerous legal domains, including civil and criminal law, as well as financial regulations such as banking acts, securities exchange laws, and tax codes. The emergence of financial technology has introduced novel scenarios not explicitly addressed by existing frameworks. Some scholars argue that Bitcoin's classification should be determined contextually within each legal system's definitions—a perspective that holds considerable merit. This article focuses specifically on examining Bitcoin's potential characteristics as a form of money, as many related legal questions appear connected to this fundamental concept.
Administrative Authority Perspectives: Not "Currency" but Possibly a "Payment Token"
The primary administrative stance comes from a joint 2013 press release by Taiwan's Central Bank and the Financial Supervisory Commission. They explicitly stated that Bitcoin is not a currency but a highly speculative digital "virtual commodity." Their reasoning rested on two main arguments: first, Bitcoin lacks the characteristics of "real currency" as measured by the three traditional functions of money—medium of exchange, unit of account, and store of value. Second, not being issued by any monetary authority, it lacks legal tender status, issuance reserves, and redemption guarantees. While this "virtual commodity" designation highlights associated risks, its precise legal implications require further exploration.
In 2018, the Central Bank, aligning with international bodies like the IMF, referred to Bitcoin and similar assets as "crypto assets" rather than "currency," emphasizing their speculative nature. It cited the Swiss Financial Market Supervisory Authority's (FINMA) guidance on Initial Coin Offerings (ICOs), which categorizes tokens based on economic function:
- Asset Tokens: Represent claims against the issuer, such as debt or equity.
- Utility Tokens: Provide access to an application or service.
- Payment Tokens: Function as a means of payment.
Under this framework, Bitcoin is primarily viewed as a payment token. The Central Bank's regulatory focus was on bringing virtual currency trading platforms under anti-money laundering frameworks. The applicability of securities laws was deemed a case-by-case determination. Subsequently, the Financial Supervisory Commission issued a ruling classifying certain security-like virtual currencies as securities under the Securities Exchange Act.
Judicial Interpretations: Not "Money" in Civil Law, but Possibly "Funds" in Banking Law
Judicial practice generally follows administrative authorities in denying Bitcoin the status of "currency." However, courts have diverged on whether it constitutes "funds" or "capital" under banking law.
The Negative View
In one fraud case, the Taiwan High Court ruled that accepting Bitcoin did not constitute illegally accepting deposits under the Banking Act. The court reasoned that the terms "funds" or "capital" within the Act are limited to items central to法定 (statutory) bank business. Since financial institutions were prohibited from handling Bitcoin, and it lacked finality of settlement within the banking system, the court held it fell outside the scope of the Banking Act. This reasoning has been critiqued for its reliance on administrative press releases rather than solid legal doctrine and for a perceived lack of clear connection between its findings on Bitcoin's nature and the legal concept of "funds."
The Affirmative View
Conversely, the Taipei District Court, in a case involving Bitcoin mining machine investments, took a purposive approach. It focused on the legislative intent behind the Banking Act to deter all forms of illegal fundraising and protect the public. The court argued that Bitcoin, being a "calculative tool with realizable value" that can be traded for cash, is functionally equivalent to other non-cash instruments used in unlawful deposit-taking schemes. Therefore, accepting it could violate the Banking Act.
A recent Supreme Court ruling aligned with this view, stating that "funds" under the Banking Act are not limited to physical currency. It held that schemes involving game tokens or virtual currencies as indirect modes of capital movement also qualify. The court noted that such assets possess economic value and represent a "transformation of legal tender," regardless of immediate convertibility.
In a separate case concerning the repayment of a Bitcoin loan, a court ruled Bitcoin was a fungible thing. The borrower was thus obligated to return an equal quantity of Bitcoin under the consumption loan contract. During enforcement proceedings, the court further elaborated that Bitcoin itself represents a certain value, enabling holders to exchange it for goods or currency, making it an object (a movable property) to which rights adhere. Consequently, the obligation to return Bitcoin was not a monetary debt and could not be enforced using methods for monetary claims. This classification of Bitcoin as a tangible object under civil law, bypassing its intangible nature, is itself a subject of significant legal debate.

Frequently Asked Questions
Is Bitcoin considered legal tender in Taiwan?
No, Bitcoin is not considered legal tender in Taiwan. The Central Bank has explicitly stated that it is not a currency because it is not issued by a monetary authority, lacks legal tender status, and does not serve as a reliable unit of account or store of value.
How do Taiwanese courts typically classify Bitcoin in legal disputes?
Courts do not classify Bitcoin as money or currency. There is a divergence in views regarding its status under banking law. Some courts see it as "funds" for the purpose of regulating illegal fundraising, while others do not. In civil matters, some judgments have treated it as a fungible item (movable property) rather than a monetary obligation.
What are the main risks identified by Taiwanese financial regulators regarding Bitcoin?
Regulators primarily highlight its high volatility and speculative nature, making it a risky investment. They also emphasize concerns about its use in money laundering, fraud, and other illicit activities due to its pseudo-anonymous nature. There is no deposit insurance or issuer guarantee backing its value.
Could owning or trading Bitcoin lead to securities law implications?
It depends on the specific characteristics of the virtual asset. The Financial Supervisory Commission has ruled that if a virtual currency possesses the qualities of a security (e.g., representing an investment contract or equity claim), it will be subject to securities laws on a case-by-case basis. Pure payment tokens like Bitcoin are generally not classified as securities.
How are Bitcoin transactions treated for tax purposes?
While the article focuses on monetary nature, transactions involving Bitcoin can have tax implications. Typically, profits from trading Bitcoin may be viewed as personal income tax. The specific treatment can depend on frequency, volume, and whether the activity is deemed occasional or professional. Always consult a tax professional for guidance.
What was the key argument from the Supreme Court that supported applying banking law to Bitcoin?
The Supreme Court adopted a functional and purposive interpretation. It ruled that the term "funds" in banking law is not restricted to physical cash. It encompasses any asset with economic value that is used as a means for raising capital from the public, including virtual currencies, as they essentially represent a transformation of legal tender value.
