The Nine Major Pitfalls Behind Virtual Assets—An In-Depth Analysis of Blockchain Fraud Phenomena

Since its birth in 2009, Bitcoin has been operating stably for over ten years. Although its original vision was to create a “peer-to-peer electronic cash system,” it has become one of the most trusted digital assets worldwide. Every day, billions of dollars’ worth of value are transferred and stored globally through Bitcoin. However, due to Bitcoin’s widespread practicality, various blockchain scam methods have also emerged, with criminals continuously exploiting the anonymity and cross-border features of virtual currencies to conduct illegal activities. As users, we must recognize these risks to effectively protect our assets.

Virtual wallets become money laundering channels—The first step in blockchain scams

In the most common blockchain scam cases, money laundering crimes top the list. Many people do not realize that providing exchange wallet addresses to scam groups is equivalent to acting as a bank account provider in traditional scams, legally known as “aiding and abetting.”

According to practical rulings by Taiwanese courts (Case No. 31 of the 109th year of review), if the public provides a KYC-verified Bitcoin wallet address to a scam group for use, even in cases where someone gives you NT$20,000 to cooperate with no clear origin, it will be deemed a violation of the Anti-Money Laundering Act and constitute aiding and abetting fraud. The law states that actions concealing the destination of criminal proceeds from fraud can be recognized as money laundering. Article 2 of the Anti-Money Laundering Act explicitly defines money laundering as “concealing or disguising the true nature, source, location, or disposition of property,” and this “indirect intent” scope is quite broad.

Therefore, when strangers誘you to provide virtual wallet addresses with high rewards, be sure to stay alert. You may inadvertently become a money laundering accomplice for the scam group and bear corresponding legal responsibilities.

Fake trading platforms to steal digital assets—Most common blockchain scam tactics

Fraud is also a significant type of blockchain scam. A typical case appears in Taiwan High Court Case No. 1014 of the 106th year of appeal, where the scam group’s methods are extremely sophisticated and worth vigilance:

First, scammers set up fake Bitcoin trading platforms to attract users to open accounts. Then, they post buy signals on the platform at prices far above market rates, misleading Bitcoin sellers into thinking someone is willing to buy at a high price. Simultaneously, the platform publishes notices of “delayed payments to sellers,” intentionally delaying to prevent victims from discovering the scam in time. When sellers start to suspect, the scammers announce “an increase in transaction fees,” prompting sellers to transfer Bitcoin into the platform for trading.

In this carefully designed blockchain scam process, scammers create fake transaction records in victims’ accounts, falsely listing cash amounts to make it seem as if the transaction was successful and new Taiwan dollars were credited. When victims request the platform to return their Bitcoin, the platform immediately issues a false announcement claiming “hacked, 435 Bitcoins stolen, unable to continue operations,” as an excuse to refuse compensation.

Similar scam tactics are rampant in the market. To protect yourself, it is strongly recommended to spend five minutes verifying the background and reputation of the platform before accepting any virtual currency transfer requests. Choose well-known and regulated exchanges for operations.

Bitcoin investment scams—A trap for collecting funds under the guise of virtual currencies

Using Bitcoin as a front for illegal fund-raising is the third major type of blockchain scam. According to Taiwan Court Case No. 139 of the 108th year of the Gold Litigation, scam groups recruit investors through Facebook groups and LINE groups, claiming that an investment of NT$1,000 can yield NT$11,000 in returns, and that each additional NT$1,000 investment increases profits by NT$5,000. Such disproportionate high-return promises clearly violate market principles.

According to Articles 29 and 29-1 of the Banking Act, non-banking entities or individuals are not allowed to conduct deposit-taking business. If any organization, under the guise of borrowing, investing, or becoming a shareholder, accepts funds from multiple or unspecified persons and promises or pays high interest, dividends, or returns that are not proportionate to the principal, it will be deemed illegal fund-raising.

It is worth noting that in such cases, the real victims are fiat currencies (TWD or USD), with Bitcoin merely serving as a lure for investors. From a legal perspective, these cases are not directly related to Bitcoin crimes, but investors are still vulnerable to losses. Illegal fund-raising crimes have consistently ranked among the top three criminal conviction types in Taiwan, with law enforcement increasing efforts to crack down on such activities.

Ransomware, hackers, and the dark web—Advanced forms of blockchain scams

Beyond the three main categories above, there are more diverse blockchain scam methods internationally:

Ransomware attacks are a significant area of Bitcoin misuse. Criminals use ransomware to encrypt or control victims’ computer data, demanding ransom paid in Bitcoin for data recovery. The instant transaction capability and anonymity of Bitcoin make it the preferred payment method for extortionists, greatly increasing the difficulty of tracing.

Exchange hacking attacks are also common. In February 2014, the globally renowned virtual currency exchange Mt.Gox was hacked, resulting in the theft of Bitcoin worth approximately 11.4 billion yen, about USD 425 million. The platform eventually filed for bankruptcy protection in Tokyo. Such incidents remind users to be extra cautious when choosing trading platforms.

Illegal pyramid schemes are often associated with Bitcoin. Some organizations recruit members mainly through referral, where earnings are not based on product promotion or sales but on continuously recruiting new members. Such behavior violates the Multi-Level Marketing Act Article 29 and carries criminal liability.

Bitcoin gambling is another emerging crime. Taiwanese police once uncovered the first blockchain gambling case, where suspects set up a betting website based on EOS blockchain technology abroad, inviting users via PTT, Facebook, and messaging apps. The suspects were prosecuted for violating Article 267 of the Criminal Code (“Operating a gambling house”).

Dark web illegal transactions represent the most extreme form of blockchain scams. The Silk Road( dark web black market once allowed customers to buy methamphetamine, cocaine, heroin, and other illegal goods using Bitcoin. Due to the scale and nature of transactions, the founder was called “the biggest drug dealer of the internet age” by a judge at the Manhattan Federal Court.

Romance scams (Pig Butchering) have rapidly grown in recent years as a form of blockchain scam. Scammers impersonate young, beautiful women, establish trust through dating platforms, and after gaining affection, induce victims into pre-designed fake investment schemes, ultimately demanding Bitcoin investments.

Self-protection guide—How to avoid blockchain scam traps

In the face of increasingly complex blockchain scams, users need to stay vigilant and build protective awareness:

First, verify any request asking for your virtual wallet address or Bitcoin transfer. If the source is unclear, never provide your personal exchange wallet address to avoid unwittingly becoming a money laundering accomplice.

Second, choose large-scale, reputable, and regulated trading platforms. Do not make large transactions or investments without thorough background checks. Any investment scheme claiming disproportionately high returns should be regarded as a red flag.

Third, be highly cautious of all proposals involving personal feelings and investments. Rapidly developing romantic relationships with strangers that suddenly mention investments are often scam signals.

Finally, regularly update your computer security software to prevent ransomware infections. If you receive suspicious files or links on your computer or phone, delete them immediately and do not open.

Rational view of technological neutrality—Reflections on blockchain scams

Although we have listed nine major types of crimes related to Bitcoin and blockchain, it is crucial to understand a core concept: Blockchain and Bitcoin are like water—they can carry a boat or overturn it. Technology itself is neutral; its good or bad depends on user behavior and intent.

The blockchain technology represented by Bitcoin is a product under specific values, but ultimately it is just a tool. Human actions determine whether it is used for legal or illegal purposes. Moral judgment should be attributed to the user, not to the technology itself. Understanding the various forms of blockchain scams is not about denying the technology but about helping users enjoy the convenience of virtual assets while effectively identifying and avoiding related risks.

By raising awareness, choosing legitimate platforms, and verifying information sources, we can explore and transact more safely in the blockchain world.
