The final gate of trading is neither technique nor psychology, but law and taxes. Once the money is made, it still has to be made legally, moved out cleanly, and kept safe — that is what decides whether your gains are "profit" or a "liability".
⚠️ Risk Warning
This article is an objective summary of regulatory and tax common knowledge, intended for learning and research only; it does not constitute legal or tax advice. Regulatory policies, tax rules, and enforcement stances change frequently; any specific conclusion in this article defers to the latest laws, official documents, and the opinion of qualified professionals. For personal deposits, withdrawals, and filing matters, consult a licensed lawyer or tax professional.
Before We Start: Three Levels of Compliance Awareness
| Level | Focus | Common misconception |
|---|---|---|
| Beginner | Is the platform legitimate? Are my funds safe? | "A big platform is automatically compliant" |
| Intermediate | Are deposit/withdrawal channels clean? Will my bank account freeze? | "As long as the money arrives, everything is fine" |
| Advanced | Tax filing, asset classification, legal liability | "If I make money, no one will ever find out" |
Compliance is not a straitjacket but a guardrail: it does not guarantee you make money, but it does guarantee that the money you make is not confiscated, not frozen, and does not bring criminal liability. We start with the regulatory picture in mainland China.
1. Mainland China's Regulation of Virtual Currencies
1.1 Key timeline and regulatory thread
| Time | Event | Key point |
|---|---|---|
| 2013 | Five-ministry "Notice on Preventing Bitcoin Risks" | Classified Bitcoin as a "virtual commodity"; financial institutions barred from related business |
| Sep 2017 ("9/4") | Seven-ministry "Announcement on Preventing Risks of Token Issuance and Financing" | Fully banned domestic ICOs, shut down domestic virtual-currency exchanges, with deadline-based exits |
| May 2021 | Financial Stability and Development Committee meeting | Crackdown on Bitcoin mining and trading; financial institutions strictly barred from related business |
| Sep 2021 | Ten-authority "Notice on Further Preventing and Disposing of Virtual-Currency Trading Speculation Risks" | Clarified that virtual-currency-related business activity constitutes illegal financial activity; overseas exchanges serving mainland users are operating illegally |
1.2 The current regulatory line (centered on the 2021 Notice)
- Virtual currencies do not have legal status equal to legal tender, are not legal tender, and the public participates "at its own risk".
- No institution may conduct business exchanging legal tender for virtual currency, issuing tokens, or trading virtual-currency derivatives; providing such services to the domestic public is illegal.
- Banks and payment institutions may not provide accounts, payment, or settlement services for virtual-currency trading (the "bank ban").
- Individuals holding and trading virtual currency sits in a civil-law "gray zone": policy discourages it, and enforcement mainly targets "service providers involved in trading" and "illegal uses such as laundering money with coins". There is currently no unified, explicit rule on criminalizing or taxing scattered peer-to-peer trading between individuals, and enforcement stances differ across regions — always defer to the latest rules.
1.3 Compliance status of overseas trading platforms
| Platform type | Compliance status (for mainland users) |
|---|---|
| Top overseas exchanges that have exited the mainland | Explicitly no longer serve mainland users; legacy accounts restricted or closed out |
| Overseas platforms still accepting mainland users | No mainland license; operating in the gray/violating zone of "serving the mainland", with service liable to be cut off at any time |
| Domestic counterfeit / copycat platforms | Black platforms — see 02-Scam Detection ④ |
Objective conclusion: for mainland residents, using overseas virtual-currency trading platforms sits in a regulatory gray zone — "not illegal" does not mean "risk-free": the platform may exit at any time, accounts may be frozen, and deposits/withdrawals may trip bank risk control. Assess and accept all the risks before participating.
2. Compliant Channels for Futures and Stock Trading
2.1 Legitimate domestic channels
| Instrument | Legitimate channel | Characteristics |
|---|---|---|
| A-shares | Licensed brokerages (securities firms) | CSRC-regulated; at most 3 accounts per person; real-name opening; third-party bank depository |
| Futures | Licensed futures companies | CSRC-regulated; live accounts verifiable at the China Futures Margin Monitoring Center; wholly licensed |
| Listed funds / options | Licensed brokerages | Options require meeting suitability requirements (capital, knowledge tests, etc.) |
Three yardsticks for telling legitimate from fake:
- The license is findable in the CSRC official website's (www.csrc.gov.cn) directory of securities and futures institutions.
- Account opening is real-name from start to finish, funds go through bank third-party depository, and there is never any "transfer to a personal account".
- Trading records and settlement statements are verifiable in official systems (the Futures Monitoring Center, brokerage account statements).
Reverse warning: "international futures", "London gold", and "overseas spot" accounts opened through domestic agents are in the vast majority of cases unlicensed, with uncontrollable fund flows — the hardest-hit zone for scams and black platforms (see 02-Scam Detection ④).
2.2 The compliance boundary of opening overseas accounts
| Channel | Compliance boundary (objective statement) |
|---|---|
| HK / US brokers (Interactive Brokers, Charles Schwab, etc.) | Locally licensed with segregated accounts, but cross-border funds must move through the person's own overseas bank card / foreign-currency account, in compliance with the state's forex administration rules (the USD 50,000-per-person-per-year convenience quota) |
| Illegal forex exchange / underground banking | Illegal. Extremely high money-laundering risk; accounts may be frozen and liability pursued |
| Domestic agents for overseas trading | Unlicensed agency constitutes illegal business operation; "overseas futures agency" offers are mostly scams |
Key point: opening an overseas account is not itself illegal, but funds must leave the country through legal channels (buy the forex yourself, in your own name, into your own account, deposited compliantly); any intermediary offering to "exchange forex and deposit for you" may be breaking the law or running a scam. The specific rules on forex quotas and cross-border fund management defer to the current regulations of the State Administration of Foreign Exchange.
3. Deposit and Withdrawal Compliance Risks
3.1 Legal risks of USDT over-the-counter (OTC) trading
- Individuals buying and selling USDT with each other sits in a civil gray area, but any of the following can touch a red line:
- The counterparty's funds come from fraud, gambling, money laundering, or other criminal activity; once you receive the money, your bank account will be frozen by judicial order (a "bank account freeze"), and you may even be found to have helped transfer criminal proceeds.
- Frequent large OTC trading is identified by financial institutions as suspicious transactions, triggering anti-money-laundering investigations.
- Doing OTC exchange as a business and earning the spread may be deemed illegally engaging in funds payment and settlement business, potentially constituting the crime of illegal business operation (final determination rests with the judicial authorities).
3.2 Typical scenarios of money-laundering-related account freezes
| Scenario | Consequence |
|---|---|
| Sell coins and receive fraud proceeds | Bank card / account frozen by the police; the funds may be recovered and confiscated |
| Take in an unexplained sum "for a friend" and pass it on | Account frozen; possible interviews and investigation assistance |
| Frequent "fast-in-fast-out" large transfers | Flagged by the bank's risk-control model; off-counter transactions restricted |
| Card receives amounts clearly above your income | Large suspicious-transaction report (TA type) triggered; source of funds checked |
Core logic: banks and law enforcement look only at the fund trail, not at your "good intentions". Once your account becomes a link in a criminal fund chain, the risk of the freeze and the liability lands on you.
4. Anti-Money-Laundering Basics: Why You Should Never Receive or Forward Coins for Others
"Just receive this for a friend", "help me move a sum through" — this may be the most expensive sentence you have ever heard. Reasons:
- You cannot verify the source of the funds: the counterparty's "legitimate money" may be proceeds of fraud, gambling, or money laundering.
- The cascading cost of a freeze: freezes can last from months to years; unfreezing requires cooperating with the investigation and proving the funds' legal origin.
- Criminal liability risk: knowingly helping transfer criminal proceeds may constitute the crime of concealing or disguising criminal gains; helping repeatedly and for profit sharply raises the risk (final determination rests with the judicial authorities).
- Your credit record and financial standing: once frozen or flagged, your loans, account opening, and cross-border fund movements are all affected.
The three "don'ts" of anti-money-laundering:
- Do not receive or forward funds of unknown origin for anyone (cash, transfers, and virtual currency all count).
- Do not lend out your bank card, your Alipay or WeChat payment QR codes, or your exchange account.
- Do not facilitate "fast-in-fast-out" abnormal transfers, no matter what benefit you are promised.
5. Tax Boundary: This Article Only Answers “When Should You Stop and Verify?”
Instrument-by-instrument rules and rates for A-shares, HK stocks, US stocks, and crypto are maintained in Tax Planning Basics. Keeping one factual home avoids two articles drifting into conflicting, outdated numbers. This compliance article retains only three action-level judgments:
- Restricted trading does not mean tax-exempt proceeds: regulatory classification and income filing are separate questions; the absence of a clear tax category does not prove permanent exemption.
- Account location does not determine tax residence: an overseas broker, exchange, or bank account does not erase residence-country filing duties. Multiple residence, double taxation, and credits require professional judgment.
- Evidence comes before calculation: retain onboarding records, funding trails, trades, fees, and withholding certificates. A precise rate cannot cure an unexplained source of funds.

6. Compliance Survival Checklist
- Trade stocks and futures only through legitimate licensed channels; for overseas trading, accept only licensed platforms, with domain and license verified on official websites.
- Treat virtual-currency trading as "gray" by default: don't promote it, don't recruit people, don't make it your business; participate only in small size and with your own money, prepared for total loss.
- Move funds only through your own legal channels: buy forex yourself, your own bank card, your own account; refuse all third parties offering to "exchange forex for you or collect/pay on your behalf".
- Never receive or forward coins for others, never lend out accounts or payment QR codes — the cost of one bank account freeze far exceeds the value of the "favor".
- Keep a complete chain for large funds: proof of the funds' source, trading records, transfer receipts — ready to explain to banks and judicial authorities at any time.
- If frozen, don't panic and don't run: cooperate with the judicial and bank investigations, honestly explain the source and use of the funds, and engage a lawyer when necessary (fleeing only deepens suspicion).
- Proactively learn your overseas tax obligations: file on time in every country where you are a tax resident; when unsure, ask a tax professional — don't wait for the tax authority to knock on your door.
- Write "compliance" into your trading plan: before every deposit, ask "how did this money come in, how will it get out, and is there a record?"
- Be wary of "compliant" packaging: licensed does not mean absolutely safe; forged licenses and false claims are still common (see 02-Scam Detection ④⑦).
- Rules change, common sense doesn't: policies get updated, but the principles "never route through personal accounts, never touch funds of unknown origin, never leave unrecorded cash" hold under any regulatory regime.
💀 Banks and law enforcement look at the fund trail, not your good intentions
Once your account becomes a link in a criminal fund chain, the risk of the freeze and the liability lands on you. Banks and law enforcement look only at the fund trail, not at your "good intentions" — receiving fraud proceeds from a coin sale, taking in an unexplained sum for a friend, frequent fast-in-fast-out transfers: any one of these can get your account frozen for months, or even get you deemed to have assisted in transferring criminal proceeds.
