Legality of USDT Trading Platforms in Different Jurisdictions
USDT (Tether) is a stablecoin pegged to the US dollar, whose value typically remains at 1 USDT ≈ 1 USD, often used as a safe-haven asset and a tool for fund transfers in the cryptocurrency market. However, the legal status and trading legality of USDT are not uniform globally but are highly dependent on the specific laws, regulations, and financial regulatory policies of each country and region.
Legality and Risks in Mainland China

Since 2017, mainland China has explicitly prohibited cryptocurrency trading and Initial Coin Offerings (ICOs) through domestic platforms. In September 2021, ten ministries and commissions, including the People's Bank of China (PBOC), further reiterated that virtual currency-related business activities are illegal financial activities, including but not limited to virtual currency exchange, trading, issuance, and financing. Therefore:
- Personal Holdings: Simply holding USDT itself has not yet been explicitly defined as illegal by law.
- Trading Activities: Buying and selling USDT through domestic or overseas platforms or using USDT for other cryptocurrency transactions are all considered illegal financial activities.
- Over-the-Counter (OTC) Trading Risks: Buying and selling USDT through OTC transactions, especially involving large sums of money or suspicious uses (such as money laundering, illegal fundraising, evading foreign exchange controls, etc.), may violate laws, leading to frozen bank accounts and even criminal liability.
- Financial Institution Restrictions: Banks and payment institutions are prohibited from providing services related to virtual currencies.
Mainland Chinese users are advised to participate in cryptocurrency-related activities with caution, strictly abide by local laws and regulations, and avoid crossing legal red lines.

Overview of Legality in Other Major Countries/Regions
- United States: USDT is recognized as a virtual currency in the US and is regulated by the Financial Crimes Enforcement Network (FinCEN) of the US Department of the Treasury. Tether has reached a settlement with the New York Attorney General's Office regarding reserve transparency issues, but USDT continues to operate compliantly in the US market.
- European Union: Under the EU's Markets in Crypto-Assets Regulation (MiCA), stablecoin issuers must meet strict transparency and reserve requirements. Given the implementation of MiCA regulations, Tether has announced that it will cease providing services in the EU region starting July 2026, while other stablecoins like USDC are actively seeking compliant pathways under MiCA.
- Japan: Japan recognizes USDT as a legal payment method or crypto asset. In Japan, USDT trading must be conducted on trading platforms registered and licensed by the Financial Services Agency (FSA).
- South Korea: USDT has a high degree of acceptance in South Korea, and many South Korean cryptocurrency exchanges offer USDT trading pairs.
- Singapore: The Monetary Authority of Singapore (MAS) considers USDT a payment token, and its issuance and trading must comply with relevant provisions of Singapore's Payment Services Act.

In summary, the legality of USDT and the use of its trading platforms is a complex global issue. Before engaging in USDT trading, users must understand and comply with the latest laws and regulations of their respective jurisdictions and be fully aware of the inherent compliance and operational risks.
