In September 2024, a Binance user sparked widespread discussion online after sharing that their account was restricted for listing cryptocurrency as their sole source of income. The exchange reportedly requested documentation such as annual income statements and tax filings—proof that many in the crypto-native community struggle to provide. With hundreds of thousands of views and intense debate, the incident highlighted a growing tension between traditional financial compliance frameworks and the realities of digital asset earners.
While Binance’s request aligns with global anti-money laundering (AML) regulations, the controversy stems from a mismatch: legacy financial systems are ill-equipped to verify wealth derived entirely from decentralized, blockchain-based activities. In this article, we’ll explore the source of wealth (SOW) and source of funds (SOF) requirements, how they apply to crypto users, and practical strategies to stay compliant—without compromising privacy or access.
Understanding Source of Wealth and Source of Funds
What Is Source of Wealth?
Source of Wealth (SOW) refers to the broader origin of an individual’s total accumulated assets. It answers the question: How did you build your net worth over time? This could include income from employment, business profits, inheritance, investments, or other legal means.
Financial institutions—including regulated crypto exchanges—must verify SOW as part of Customer Due Diligence (CDD) under AML/CFT (Anti-Money Laundering / Countering the Financing of Terrorism) frameworks.

Common Sources and Required Documentation
Exchanges like Binance typically accept the following proofs:
- Salary income: Recent pay stubs or bank statements showing employer deposits.
- Self-employment: Invoices, contracts, or audited profit/loss statements.
- Investment returns: Brokerage statements or dividend records.
- Property sales: Sale agreements or closing documents.
- Inheritance or gifts: Legal wills or notarized donation letters.
- Crypto mining or trading: Platform-generated trade histories, wallet activity logs, and proof of equipment purchases (for miners).
For crypto-native earners—such as full-time traders, DeFi yield farmers, or NFT creators—the challenge lies in translating on-chain activity into acceptable off-chain documentation.
The Role of SOW in Global Financial Compliance
Why SOW Matters
Regulatory bodies like the Financial Action Task Force (FATF) mandate SOW verification to:
- Prevent money laundering and terrorist financing.
- Ensure financial system integrity.
- Enable cross-border transparency through international cooperation.
SOW is not just about stopping crime—it also supports tax compliance and helps governments track capital flows across jurisdictions.
How SOW Intersects with Tax Reporting
When users fail to report crypto gains, they risk triggering red flags during SOW reviews. Even in countries with unclear crypto tax guidance, exchanges may still require proof tied to declared income. This creates friction for those who:
- Earn exclusively through crypto trading.
- Lack formal employment records.
- Operate across borders using decentralized tools.
Without proper documentation, accounts can be frozen—or worse, permanently restricted.
Regional Regulatory Approaches to Source of Wealth
United States
Under the Bank Secrecy Act (BSA) and the 2020 Anti-Money Laundering Act, U.S. financial institutions must collect detailed SOW information. The Financial Crimes Enforcement Network (FinCEN) oversees enforcement.
Key expectations:
- Full transaction trail for large deposits.
- Linkage between on-ramp fiat inflows and crypto activity.
- Reporting of suspicious patterns via SARs (Suspicious Activity Reports).
Digital records are acceptable if they meet ESIGN Act standards for authenticity.
European Union
The EU operates under the 6th Anti-Money Laundering Directive (6AMLD), requiring member states to implement strict KYC and SOW protocols.
Notable features:
- Mandatory use of eIDAS-compliant electronic signatures for digital proofs.
- Risk-based approach: Higher scrutiny for high-net-worth individuals and cross-border transfers.
- Requirement for notarization or certification of certain documents.
Crypto Asset Service Providers (CASPs) fall directly under these rules post-MiCA regulation.
China
China maintains a strict regulatory stance, banning cryptocurrency transactions while promoting state-backed digital currency (e-CNY). Under the Anti-Money Laundering Law and related guidelines:
- All financial institutions must conduct internal risk assessments.
- Cross-border data flows are tightly controlled under the Data Security Law.
- While crypto trading is prohibited domestically, offshore holdings may still trigger reporting obligations for residents.
Why Crypto Challenges Traditional SOW Systems
Decentralization vs. Centralized Verification
Blockchain’s core innovation—decentralization—clashes with centralized compliance models. There's no employer issuing paychecks or bank confirming deposits. Instead, value is generated peer-to-peer, often pseudonymously.
This makes it difficult to:
- Link wallet addresses to real-world identities.
- Prove consistent income without third-party validation.
- Demonstrate long-term wealth accumulation through standardized forms.

Borderless Transactions and Jurisdictional Gaps
Crypto moves freely across borders, but regulations do not. A trader in Southeast Asia might earn USDT from a protocol based in Switzerland, pay taxes nowhere, and withdraw funds to a European bank—all outside traditional oversight channels.
Regulatory arbitrage creates compliance blind spots—and increases scrutiny when fiat off-ramps occur.
Volatility and Valuation Complexity
Unlike stable salary income, crypto earnings fluctuate hourly. A $50,000 profit today could be $30,000 tomorrow. Exchanges struggle to assess true income levels when valuations swing wildly.
Moreover, different asset types—Bitcoin, stablecoins, governance tokens—carry varying risk profiles under AML frameworks.
Tax Ambiguity Fuels Compliance Risks
Many crypto earners assume no reporting is needed if there's no formal job. But most jurisdictions treat crypto gains as taxable events—even for full-time traders.
Failure to file leads to:
- Mismatched SOW declarations.
- Increased audit risk.
- Potential account freezes during exchange reviews.
How to Prove Crypto Income Legitimately
Despite the challenges, proactive steps can ensure smooth compliance:
1. Maintain Detailed Transaction Records
Export complete trade histories from all exchanges and DeFi platforms. Include:
- Timestamps
- Token amounts
- USD values at time of transaction
- Wallet addresses involved
Use tools like Koinly, CoinTracker, or Accointing to generate audit-ready reports.
2. Convert Profits Regularly to Fiat
Regular withdrawals to a personal bank account create a clear paper trail. These transfers serve as indirect proof of income when paired with exchange statements.

3. File Taxes Proactively
Even in low-regulation environments, self-reporting builds credibility. Treat crypto income like freelance earnings:
- Estimate annual profits.
- Pay estimated taxes quarterly if required.
- Keep official receipts and filings on record.
4. Use Regulated On-Ramps and Exchanges
Stick to licensed platforms that provide certified statements. These often include:
- Verified transaction summaries
- Platform-branded PDF exports
- Audit-compliant metadata
Avoid mixing funds from unhosted wallets unless absolutely necessary.
5. Prepare a Personal Wealth Narrative
Write a concise summary explaining your journey:
“I began trading cryptocurrencies in 2021 with an initial investment of $5,000. By 2023, I transitioned to full-time trading across centralized and decentralized platforms, achieving consistent returns through technical analysis and yield farming.”
Pair this narrative with transaction logs and tax filings for maximum credibility.
Frequently Asked Questions (FAQ)
Q: Do I need to prove where every coin came from?
A: Not necessarily every transaction—but exchanges typically require proof for large deposits or sudden balance increases. Focus on documenting significant inflows.
Q: Can I use blockchain explorers as proof?
A: Partially. While explorers show transparency, exchanges usually require compiled reports from known platforms or certified documents. Use explorers to support your case, not replace formal proof.
Q: What if I didn’t pay taxes on past crypto gains?
A: Consult a tax professional immediately. Some jurisdictions allow voluntary disclosure programs with reduced penalties. Rectifying past omissions strengthens future SOW submissions.
Q: Does staking or yield farming count as income?
A: Yes, in most legal frameworks. These are treated as earned income or investment returns and should be recorded accordingly.
Q: Can I get locked out of my account permanently?
A: Yes, if you fail repeated verification requests. Always respond promptly and submit whatever documentation you can—even incomplete records are better than none.
Q: Are decentralized exchanges safer for privacy?
A: They offer more anonymity initially, but once you cash out via a regulated entity (like a bank), you’ll still need to justify fund origins. True privacy requires advanced operational security—and carries higher compliance risks.
Final Thoughts
As digital assets reshape how people earn and store value, legacy financial systems are playing catch-up. The Binance case reflects a broader shift: crypto is no longer fringe—it's subject to real regulatory scrutiny.
By embracing transparency, maintaining meticulous records, and engaging responsibly with tax authorities, crypto-native individuals can navigate SOW requirements successfully. The future belongs to those who operate openly within evolving frameworks—not outside them.
The key takeaway? Proof of wealth isn’t about invasion of privacy—it’s about inclusion in the global financial system. Those who prepare now will face fewer barriers tomorrow.
