Introduction
In September 2024, a Binance user reported on social media that their account was restricted after citing cryptocurrency as their sole income source. The exchange requested annual income proof and tax documentation, sparking widespread debate. This incident highlights tensions between traditional Proof of Source of Wealth (SOW) systems and crypto-centric financial models. Below, we analyze SOW frameworks and provide actionable solutions for crypto holders.
1. Proof of Source of Wealth (SOW) Explained
1.1 Definition and Purpose
SOW verifies the legitimacy of accumulated assets—from salaries to investments—to mitigate fraud and money laundering risks. Financial institutions require documents like tax returns, bank statements, or business records to validate wealth origins.
1.2 Common Asset Types and Documentation
Binance’s guidelines outline accepted proofs for various assets:
| Asset Type | Documentation Required |
|---|---|
| Salary | Pay stubs, bank statements, tax returns |
| Self-Employment | Invoices, contracts, or annual tax filings |
| Cryptocurrency Mining | Equipment receipts, 3+ months of transaction logs |
2. Global SOW Regulations Compared
2.1 Key Jurisdictions
- United States: Governed by AML Act (2020) and BSA. Requires detailed transaction histories.
- European Union: Follows AMLD6, mandating KYC checks and suspicious activity reporting.
- China: Enforces anti-money laundering laws via PBOC, with strict digital asset oversight since 2023.
2.2 Compliance Challenges
- Decentralization: Crypto’s anonymity complicates traditional SOW tracking.
- Cross-Border Flows: Varying regulations across jurisdictions create compliance gaps.
3. Proving Crypto Asset Legitimacy
3.1 Best Practices
- Maintain detailed transaction records (dates, wallet addresses).
- Convert crypto gains to fiat via regulated exchanges to establish audit trails.
- File tax returns proactively, even in crypto-friendly regions.

3.2 Tools for Transparency

- Leverage regulated exchanges for compliance-ready reporting.
FAQs
Q1: Why did Binance restrict my account?
Binance enforces SOW policies to comply with global AML laws. Restrictions often follow unflagged crypto-only income claims.
Q2: How can I prove crypto mining income?
Provide purchase receipts for mining hardware and platform-generated income logs spanning 3+ months.
Q3: Are stablecoins treated differently under SOW?
Yes. Stablecoins tied to fiat may simplify valuation but still require standard proof of origin.
Conclusion
Cryptocurrencies challenge conventional SOW frameworks but adapting with transparent practices ensures compliance. As regulators refine policies, crypto users must prioritize documentation and legal adherence.
