Cryptocurrency scams are incredibly common. Today, we will temporarily set aside highly technical methods such as Decentralized Exchanges (DEX), cross-chain technology, or coin mixers. In the author's extensive experience handling these cases, the use of such advanced technologies for committing crimes or money laundering is not the most common scenario. On the contrary, the vast majority of cases involve funds being transferred in the form of USDT between decentralized wallets, ultimately entering a Centralized Exchange (CEX) for withdrawal, or being cashed out through Over-The-Counter (OTC) merchants.

Why Do Most Scam Syndicates Avoid "High-Tech" Money Laundering?

Indeed, most fraud syndicates do not necessarily understand DEX, cross-chain protocols, or mixers, nor are they necessarily willing to use them. The reason is highly practical: these all represent costs.

High-level technology requires professionals, which implies higher labor costs. These technologies also incur transaction fees and come with the risks of "fat-finger" (operational) errors, time consumption, and even having funds stuck in cross-chain bridges or smart contracts—none of which are trivial matters for scammers. Furthermore, complex technical workflows make it difficult to establish Standard Operating Procedures (SOPs). Therefore, the use of profound technologies is mostly left to professional hackers, typically seen in scenarios where specific exchanges or projects are hacked, and the hackers rapidly transfer and conceal funds using these techniques.

Core Concept: It’s Simply the "On-Chain Version of Traditional Financial Fraud"

In other words, many cryptocurrency fraud cases are essentially replicas of traditional scams: On-chain wallet addresses are exactly like traditional "dummy bank accounts," and withdrawing funds at a CEX is just like "money mules withdrawing cash at an ATM" in traditional scams.

Why is USDT the Favorite of Scam Syndicates?

Why is the "USDT remains USDT" transfer model so common? Because USDT is the cryptocurrency tool closest to cash. It boasts excellent liquidity, price stability, easy OTC processing, and broad support across almost all exchanges. For scam syndicates, USDT is the ultimate "cash-out channel." They don't have to worry about the high volatility of Bitcoin, nor do they need to worry that a wallet or exchange might not accept a rare altcoin. USDC might offer similar advantages, but USDT holds a certain "historical sentiment" for fraud rings and gray industries.

In practice, we see many seemingly complex but actually very "mechanical" moving processes: splitting funds into multiple transactions, scattering them across several different addresses, merging them again, splitting them once more, and after several transfers, dumping a portion into Exchange A and another into Exchange B. This technique, known as "Layering," aims to obscure characteristics and lower the suspiciousness of single transactions; the more layers of splitting, the harder it is for law enforcement to track.

The Key to Recovering Funds: It's Not About Tracing to the Very End, But "Finding an Actionable Node"

When facing complex financial flows, the key to tracking is not actually "tracing to the last moment," but finding a "node where legal action can be applied."

We typically break down the feasibility of recovering funds into two core dimensions:

Traceability:

Can the path of the fund transfers on the blockchain be completely mapped out?

Recoverability:

Can we freeze accounts, seize funds, or subpoena user data at a specific critical node?

In mainstream cases, the most common actionable node is the CEX (Centralized Exchange). This is because scam syndicates ultimately need to convert cryptocurrency into fiat currency. While OTC merchants (or various OTC platforms) are certainly an avenue, the most stable and large-scale cash-out venues are still the exchanges.

Traditional Fraud vs. Cryptocurrency Scam Money Flow Comparison

Comparison Item	Traditional Financial Fraud	Cryptocurrency Fraud (On-Chain Version)
Fund Storage Point	Dummy Bank Accounts	Decentralized Cold/Hot Wallet Addresses
Transaction Proof	Bank Remittance Records / Passbook Details	On-Chain Transaction Records (Tx Hash)
Money Laundering Method	Interbank Transfers, Multi-Layer Dummy Account Laundering	Layering, Splitting, and Merging
Cash-Out Endpoint	Money Mules Withdrawing Cash at ATMs	Transferring Crypto to a CEX, OTC, or Merchant to Cash Out

Breaking Through Practical Dilemmas: Why Are Cases Often "Closed Prematurely"?

Common Reasons for Case Closure in Practice

Regrettably, in current judicial practice, we have indeed encountered many cases where prosecutors, upon seeing funds pass through one or two wallet layers, readily conclude that the funds have been "commingled" or belong to a "bona fide third party." Coupled with the difficulty of identifying the perpetrators and the challenges of tracing, cases are ultimately closed.

However, if we apply the traditional banking analogy, the logic becomes very clear: if a victim's money is transferred from Account A to B, then to C, and finally withdrawn at Account D, we would absolutely not claim it is "impossible to convict" or "impossible to trace" just because of the intermediate transfers. Isn't the most commonly caught money mule in practical fraud cases operating on the exact same concept? The core spirit of investigation remains linking the "money flow" with the "withdrawal point" to determine the destination of the criminal proceeds and the division of labor within the scam syndicate.

The on-chain world operates on the same principle: A Tx Hash (Transaction Hash) is a highly credible, verifiable proof of money flow. If we can trace the funds to ultimately correspond with a CEX deposit or withdrawal node, we theoretically possess a very concrete investigative route.

CEX KYC is Becoming Stricter, Leaving Flaws at the Withdrawal End

In recent years, global major exchanges have progressively strengthened their KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations. The clues scam syndicates might leave at the withdrawal end are actually much more abundant than before. This includes identity data, historical transaction records, login IP addresses, device information, destinations of withdrawn funds, and linked accounts. These are all powerful investigative leads.

Furthermore, most common international CEXs have offices or compliance contacts in Taiwan. The author also knows many legal personnel stationed in Taiwan; at the very least, when facing lawful data requests or inquiries from our country's law enforcement agencies, these exchanges generally do not intentionally make things difficult and are mostly willing to cooperate.

The Value of a Professional Lawyer: Translating "On-Chain Language" into "Prosecutorial Language"

Whether funds can be successfully recovered largely depends on how quickly our judicial system adapts to understanding emerging technologies. However, this also strongly highlights the value of a professional cryptocurrency lawyer: clearly explaining complex on-chain concepts and organizing them into a format that investigative agencies can directly utilize.

If lawyers themselves cannot clearly explain the concept that "USDT Layering + CEX Withdrawal ≈ Money Mule Cash Withdrawal" to prosecutors, how can we expect overwhelmingly busy law enforcement agencies to invest significant additional time to unravel the case?

When facing cryptocurrency fraud, the most common mistake victims make is often not "lacking technical knowledge," but rather "doing the right things too late," missing the golden window to preserve evidence or apply for asset freezes in the very first instance.

Frequently Asked Questions (FAQ)

Q1: My USDT was transferred to several unknown decentralized wallets. Does this mean it can never be recovered?

A: Not necessarily. Scam syndicates often use "layering" to scatter characteristics and increase tracking difficulty. However, as long as professional on-chain tracking maps out the money flow path (Traceability) and locates the Centralized Exchange (CEX) node where the funds ultimately flowed, there is still a chance to subpoena suspect information or even seize the funds.

Q2: The police and prosecutors say the money flow has passed through too many hands, making it impossible to prove it's my money, and they plan to close the case. What should I do?

A: This is a common dilemma in our country's legal practice. We strongly recommend consulting or appointing a lawyer with blockchain expertise as early as possible. They can organize the on-chain transaction records (Tx Hash) into clear proofs of money flow and explain to the investigators that this is akin to "multi-layer dummy account transfers" in traditional scams, providing concrete investigative directions and leverage points (e.g., requesting KYC data from specific exchanges).
