Cryptocurrency Scam Types and Prevention Methods: Essential Guide to Avoid Losses

Why Are Cryptocurrency Scams So Common?

Cryptocurrency scams have become increasingly prevalent due to the fundamental characteristics of digital assets: decentralization, irreversible transactions, and anonymity.

Decentralization means there is no centralized authority to report suspicious transactions to. Thanks to blockchain technology, transactions cannot be reversed once confirmed. Users communicate through wallet addresses, making tracking difficult. The anonymity of cryptocurrency users is another significant factor. Since users interact through wallet addresses rather than legal names, those who wish to maintain anonymity find it relatively easier to evade tracking compared to traditional finance.

These characteristics create an environment where scammers can operate with reduced risk of detection and prosecution, making the cryptocurrency space particularly vulnerable to fraudulent activities.

Types of Cryptocurrency Scams

There are numerous types of cryptocurrency scams, but the 15 most common include:

• Social Engineering Scams
• Phishing Scams
• Fake Apps and Cryptocurrency Exchange Websites
• Giveaway Scams
• Investment Scams
• Pump and Dump Schemes
• Romance Scams
• Blackmail and Extortion Scams
• Upgrade Scams
• SIM Swap Scams
• Cloud Mining Scams
• Fraudulent Initial Coin Offerings
• Celebrity Endorsement Scams
• Rug Pulls
• Impersonation Scams (Companies, Government, and Employment)

Let's examine each scam type in detail.

Social Engineering Scams

Social Engineering Scams use psychological manipulation techniques to deceive people and obtain confidential information related to their user accounts. Scammers may impersonate trusted entities such as government agencies, corporations, technical support teams, colleagues, or friends to gain the victim's trust.

Scammers invest time in building trust with potential victims. Once trust is established, they may request sensitive information or ask victims to transfer funds to their digital wallets. If a seemingly trustworthy organization requests cryptocurrency for any reason, it is highly likely to be a scam.

For example, in February of a recent year, Trust Wallet, owned by a major exchange, revealed that it suffered a loss of approximately $4 million due to a social engineering attack by an organized crime group. The scam was conducted in person, resulting in cryptocurrency being stolen from Trust Wallet belonging to Webverse, a metaverse startup. This case demonstrates how sophisticated and varied social engineering attacks can be, extending beyond digital interactions to face-to-face manipulation.

Phishing Scams

Phishing scams specifically target online cryptocurrency wallets. The individuals or groups behind these scams attempt to discover the private keys of wallets, which grant access to the funds stored within. Scammers often send emails containing fake website links, requesting owners to enter their private keys. Once this information is obtained, they can steal the cryptocurrency. Phishing scams are among the most frequently used tactics by scammers.

These attacks have become increasingly sophisticated, with scammers creating nearly identical replicas of legitimate exchange websites and wallet interfaces. They may use urgent language suggesting account security issues or limited-time opportunities to pressure victims into acting quickly without proper verification.

Fake Apps and Cryptocurrency Exchange Websites

Scammers create fake cryptocurrency trading platforms or cryptocurrency wallets to deceive victims. These websites typically use domain names very similar to the websites they are imitating, making them extremely difficult to distinguish. Fake cryptocurrency websites generally operate through phishing sites or theft.

Phishing pages request users to enter data necessary to access their cryptocurrency, such as wallet passwords, recovery phrases, and other financial information, which is ultimately delivered to the scammers.

Other websites simply steal funds directly. These websites initially operate normally and may even allow small withdrawals at first. If the investment seems to be going well, you may decide to invest more money in the website. However, when you later try to withdraw money, the website shuts down or refuses the request.

Another popular tactic scammers use to deceive investors is creating fake apps available on Google Play and the Apple App Store. Although these fake apps are quickly discovered and removed, they can still significantly impact many users' finances. Victims often realize the fraud only after substantial losses have occurred.

Giveaway Scams

Giveaway scams occur when scammers claim they will distribute cryptocurrency as a prize or offer even larger amounts in return for a small initial payment.

Scammers cleverly craft messages that appear to be from legitimate social media accounts, creating a sense of legitimacy and urgency. They promote what they call a once-in-a-lifetime opportunity, urging people to quickly transfer funds for massive returns.

These scams often impersonate well-known figures in the cryptocurrency space or legitimate projects, using stolen or manipulated images and branding to appear authentic. The urgency created in these messages is designed to prevent victims from conducting proper due diligence.

Investment Scams

Investment scams promise enormous returns in exchange for cryptocurrency deposits. Scammers position themselves as investment managers for new cryptocurrency projects about to launch, luring people with guarantees of substantial profits.

These schemes often present elaborate business plans, professional-looking websites, and fabricated testimonials from supposed successful investors. They may claim to have insider information or proprietary trading strategies that guarantee returns, which is a clear red flag as no legitimate investment can guarantee specific returns.

Pump and Dump Schemes

Pump and dump schemes are another type of investment scam. Scammers entice investors to purchase little-known cryptocurrencies at low prices, convincing them that the value will soon skyrocket. Then, immediately after purchase, the price does indeed surge. At this point, scammers sell their holdings at the new high price. This causes the value to plummet, creating victims.

Investors seeking quick profits are deceived by fake news claiming they can achieve tremendous returns in a short period. These scams usually start on social media. Be cautious of people who suddenly contact you talking about cryptocurrency assets. Be wary of individuals on social media platforms like Reddit or Twitter who excessively promote specific cryptocurrency assets, as they may be conducting social engineering scams.

These schemes often involve coordinated groups working together to create artificial hype and trading volume, making the manipulation appear like genuine market interest.

Romance Scams

Some scammers meet people on dating websites and engage in fraudulent activities while dating them.

Once trust is built with the other person, scammers initially talk about profitable cryptocurrencies. Later, they strengthen the bond with the other person by claiming to provide exclusive information about high-return speculative coins, then have them send personal information such as account verification credentials. The scammer then steals the victim's funds. According to the U.S. Federal Trade Commission, victims who paid cryptocurrency to romance scammers totaled $139 million in a recent year.

These scams are particularly insidious because they exploit emotional connections and can continue for months before the financial fraud occurs, making victims more vulnerable and less likely to recognize the warning signs.

Blackmail and Extortion Scams

Scammers send blackmail emails using social engineering techniques. They threaten users via email, claiming they have records of visiting adult or illegal websites, to obtain private keys. Or they threaten to expose illegal activities unless cryptocurrency is sent. Such attempts constitute criminal activity and should be reported to the police.

These scammers may claim to have compromising photos, videos, or browsing history and demand payment in cryptocurrency to prevent disclosure. They create a sense of panic and shame to pressure victims into paying quickly without thinking rationally.

Upgrade Scams

Cryptocurrency platforms, like other software, undergo updates. Scammers can exploit this fact to entice users to provide their cryptocurrency wallet's private keys.

Upgrade scammers may exploit well-known events such as the Ethereum upgrade from several years ago. The Ethereum Foundation and certain platforms have warned users about upgrade scams due to their seriousness.

Scammers may send notifications claiming that users must "verify" their wallets or "migrate" their assets to a new version, providing links to fake websites designed to capture private keys and seed phrases.

SIM Swap Scams

SIM swap scams are among the latest cryptocurrency scams. Scammers gain access to a copy of a user's SIM card, allowing them to access all data on the mobile phone.

Scammers can use this data to receive two-factor authentication codes without the user's knowledge and exploit them. Victims may have their cryptocurrency accounts hacked and deleted without their knowledge.

This type of attack is particularly dangerous because it bypasses one of the most common security measures - SMS-based two-factor authentication. Once scammers control the phone number, they can reset passwords and access accounts across multiple platforms.

Cloud Mining Scams

Cloud mining refers to users renting mining hardware from a specific company for a fixed fee and a portion of expected profits. This allows miners to mine remotely without purchasing expensive mining hardware.

However, many cloud mining companies engage in fraudulent activities or are more inefficient than expected. Investors often lose money or earn less profit than anticipated.

Legitimate cloud mining operations do exist, but the industry is rife with scams that simply take deposits and provide no actual mining services, or provide returns that are far below what was promised.

Fraudulent Initial Coin Offerings

Cryptocurrency-based investments, including initial coin offerings and non-fungible token scams, provide additional opportunities for scammers to defraud users. Emerging cryptocurrency companies raise funds from future users through ICOs by offering new cryptocurrency coins at a discount in exchange for active cryptocurrencies like Bitcoin. However, many ICOs have proven to be scams.

For example, scammers may create fake websites for ICOs and request users to transfer cryptocurrency to compromised wallets. In other cases, the ICO itself may be responsible. Founders may distribute unregulated tokens or mislead investors through false advertising.

While cryptocurrency-based investments or business opportunities may seem profitable, it is important to recognize that reality is not always as it appears. Thorough research and verification of the team, technology, and business model are essential before investing.

Celebrity Endorsement Scams

Celebrity endorsement scams are another tactic in cryptocurrency fraud. Developers pay famous actors or internet celebrities to promote coins or platforms. After attracting investors this way, they suddenly abandon the project.

In some cases, scammers may use manipulated images, videos, or websites to claim that celebrities endorsed their project.

These scams exploit the trust and influence that celebrities have with their audiences. Victims may believe that if a trusted public figure endorses a project, it must be legitimate, without realizing that the endorsement is either fabricated or that the celebrity was misled about the project's true nature.

Rug Pulls

Rug pulls derive from the expression "pulling the carpet." It refers to developers luring investors with a new cryptocurrency project (usually decentralized finance or non-fungible tokens), then abandoning the project before completion.

The non-fungible token market experienced explosive growth in a recent year, becoming a breeding ground for these scams. Many scammers deceived investors by presenting fantastic plans with no feasibility and absconded with investment funds.

Zagabond, the founder of the blue-chip Azuki NFT collection, admitted in a recent year to being behind rug pulls worth millions of dollars. At the time, he revealed how fraudulent activities occurred in three NFT collections - CryptoPhunks, Tendies, and CryptoZunks - causing widespread chaos.

Rug pulls can often take the form of Ponzi schemes, where investors continue to attract dishonest financial backers. Rug pulls can also occur in proof-of-stake projects that entice users to stake tokens in master nodes, only to have the developers drain the liquidity pools and disappear with the funds.

Impersonation Scams

Scammers may impersonate companies or other trustworthy and well-known institutions, telling people to purchase and send cryptocurrency. They may attempt to contact victims through text messages, phone calls, emails, social media, or pop-up notifications on computers.

Scammers claim that fraud has occurred in the account or that money is at risk, instructing victims to purchase cryptocurrency and send it to resolve the issue. They may also request that details be entered on fraudulent websites. Clicking links in messages or calling numbers displayed in pop-ups will connect you with scammers.

Often, these scammers may try to deceive people into purchasing new coins supposedly just issued by famous companies. It is important to verify whether the company has issued coins or tokens or conducted an airdrop.

Additionally, scammers may impersonate government agencies, law enforcement, or utility companies, claiming that legal issues need to be resolved or debts must be repaid. They instruct victims to purchase cryptocurrency and send coins to specific wallets. Or they guide victims to cryptocurrency ATMs and explain how to convert money into cryptocurrency.

Finally, scammers may recruit investors by pretending to recruit jobs through job sites, having them sell and mine cryptocurrency and convert cash into cryptocurrency. They instruct victims to withdraw some money and purchase cryptocurrency for fictitious customers. By this point, the money disappears, leaving only the responsibility to repay the bank.

Recent Cryptocurrency Scams

In recent years, several cryptocurrency scam cases have occurred globally. Here are representative examples:

In one notable case, an individual posing as a cryptocurrency expert approached a famous internet broadcaster on a streaming platform by sending virtual gifts to gain attention. After the broadcaster shared difficulties regarding stock and cryptocurrency investment failures, their relationship grew closer. Shortly thereafter, the scammer boasted about a cryptocurrency balance showing substantial funds and recommended investing in a new project guaranteeing high returns. The broadcaster transferred a significant amount. However, it was all a scam. Eventually, the court sentenced the scammer to five years in prison for fraud under special economic crime laws.

Additionally, police investigated fraud allegations against a blockchain sports platform. According to media reports, the platform allegedly attracted well-known celebrities to lure more investors in fraudulent activities. However, the celebrities mentioned in connection with this case strongly denied any involvement with the project.

In another period, when Bitcoin prices broke previous highs and rose significantly, financial regulatory authorities issued press releases urging caution against cryptocurrency scams. Regulators emphasized that scammers induce users to use specific trading sites or install apps through social media or chat rooms, then confuse users into thinking they are using legitimate exchanges while conducting fraud.

How to Identify Cryptocurrency Scams

Scammers are becoming increasingly sophisticated, and it is easy to fall victim online. To recognize cryptocurrency scams, watch for these warning signs:

• Promises of Future Returns. No investment can guarantee future returns. If someone guarantees you will make money through cryptocurrency, this is a warning sign.
• Poorly Written or Non-existent Whitepaper. A whitepaper is a crucial element in any cryptocurrency project. This document should explain how the cryptocurrency is designed and how it works. If the whitepaper is incomprehensible or does not exist, this is a red flag.
• Extreme Marketing. Most fraudulent projects rely heavily on marketing. Their strategies include paid online advertising, paid influencers, and even offline promotion.
• Anonymous Team. You should be able to easily find biographical information about key figures behind an investment and verify their presence on social media to know who is running the investment. Be cautious if you cannot determine who is behind the cryptocurrency.
• Free Money. Any investment opportunity promising free money, whether cash or cryptocurrency, is likely a scam.

How to Avoid Cryptocurrency Scams

Here are several methods to prevent cryptocurrency scams:

• Keep Your Wallet Secure. Always store cryptocurrency in self-hosted wallets rather than on exchanges, and never share your private keys with others.
• Avoid Random Messages and Calls. Do not be intimidated by people contacting you about cryptocurrency investment opportunities from unclear sources. Be careful not to provide personal information or transfer amounts from unknown sources.
• Don't Be Tempted by Offers That Are Too Good. Scammers often make false promises about unrealistic investment returns. Never use offers claiming you can become rich in a short period, as most are scams.
• Urgent Investment Opportunities. Do not rush into investment decisions without conducting sufficient due diligence and taking time to thoroughly research all options. Make careful decisions based on adequate information.
• Be Cautious of Social Media Hype. Scammers often use social media to advertise new scams and present them as investment opportunities. Be wary of advertisements using images of celebrities to make investments appear legitimate.

What to Do If You've Been Scammed

If you have fallen victim to a cryptocurrency scam and shared personal information or made payments, it is important to take immediate action.

If you used a bank card or shared sensitive information with scammers, contact your bank immediately. Scammers may attempt to target you again or sell your personal information. Therefore, it is important to change security information and passwords, especially for online banking.

How to Report Cryptocurrency Scams

If you suspect a cryptocurrency scam or have been victimized, seek help from your country's financial crime authorities. You can also file complaints or report scams to the following agencies:

• Local Police Department
• Cybercrime Reporting Systems
• Financial Regulatory Authorities
• Internet Safety Organizations

These agencies can provide guidance on next steps and may be able to investigate the fraud, though recovery of lost funds remains challenging in most cases.

Prevention Is the Best Defense Against Cryptocurrency Scams

As cryptocurrency adoption increases in mainstream society, scams are also proliferating. The Web 3.0 ecosystem is filled with malicious actors. Everyone using cryptocurrency must always be vigilant against fraudulent activities. Learn about cryptocurrency scam types in advance and be sure to prevent them.

Staying informed about the latest scam tactics, maintaining healthy skepticism about investment opportunities that seem too good to be true, and taking proper security measures with your digital assets are essential practices for anyone participating in the cryptocurrency space. Remember that legitimate projects and platforms will never pressure you to act immediately or request your private keys and sensitive information.
