As the cryptocurrency market evolves, so do the strategies of scammers. From classic Ponzi schemes to sophisticated tactics, these scams adapt to exploit the enthusiasm of investors. In this article, we’ll explore these fraudulent schemes, empowering you with knowledge to protect your investments and personal information in the ever-changing world of cryptocurrencies.

The Current State of Crypto Crime

According to Chainalysis, contributions to unauthorized addresses have decreased across almost all sectors, with scams witnessing the most substantial decline. Until June 2023, the earnings from cryptocurrency scams were about $3.3 billion less compared to the same period in 2022, totaling slightly above $1.0 billion this year.

Conversely, ransomware appears to be the sole category of crypto-related crime projected to escalate in 2023, with culprits having seized $175.8 million more than the corresponding period last year. This increment in annual earnings potentially signifies a setback to the optimistic decline in ransomware activities observed in 2022.

Types of Crypto Scams

It’s essential to be aware of the different types of scams and the red flags associated with them to protect yourself in the cryptocurrency market. Here are some of the most prominent ones:

1. Phishing Scams

Phishing scams are a prevalent form of cryptocurrency fraud. Scammers create fake websites or send deceptive emails that mimic legitimate cryptocurrency exchanges or wallet providers. These fake sites or emails often ask users to enter their private keys, passwords, or other sensitive information.

How to Avoid Phishing Scams:

  • Always verify the authenticity of the website’s URL. Ensure that you are on the correct website by manually typing in the web address or using bookmarks.
  • Be cautious of unsolicited emails or messages, especially those that request sensitive information.
  • Use hardware wallets or offline storage solutions to protect your cryptocurrency assets. These wallets are less susceptible to online phishing attacks.

2. Ponzi Schemes

Ponzi schemes promise investors significant returns on their investments with little or no risk. These scams rely on funds from new investors to pay returns to earlier investors, creating the illusion of a profitable venture. Ponzi schemes eventually collapse when there are not enough new investors to sustain payouts.

How to Avoid Ponzi Schemes:

  • Be skeptical of investment opportunities that guarantee high returns with no associated risks. If it sounds too good to be true, it probably is.
  • Research the company or individual behind the investment thoroughly. Look for credible reviews, news articles, and regulatory information.
  • Consult with trusted financial advisors or conduct due diligence before investing in any opportunity.

Initial Coin Offering - ICO

3. Fake ICOs (Initial Coin Offerings)

Fake ICOs involve scammers creating fraudulent cryptocurrency projects and tokens. They market these projects as groundbreaking opportunities, enticing investors to purchase tokens that are either worthless or non-existent. Once they’ve collected a significant amount of funds, the scammers disappear.

How to Avoid Fake ICOs:

  • Research the ICO project extensively, including the backgrounds of the team members and advisors. Legitimate projects should have transparent information about their team.
  • Verify the legitimacy of the ICO by checking reputable cryptocurrency news sources, forums, and community feedback.
  • Exercise caution when faced with ICOs that promise guaranteed profits. No investment is entirely risk-free.

4. Pump and Dump Schemes

Pump and dump schemes manipulate the price of a cryptocurrency through false information and coordinated buying activity. Scammers artificially inflate the price to attract unsuspecting investors. Once the price reaches a peak, they sell off their holdings at a profit, causing the price to plummet.

How to Avoid Pump and Dump Schemes:

  • Avoid making impulsive investment decisions based on social media hype or sudden price surges.
  • Research the cryptocurrency thoroughly before investing. Look for real-world use cases, development activity, and the project’s community reputation.
  • Be cautious of any cryptocurrency that experiences drastic, unexplained price increases.


Cryptojacking is a form of cryptocurrency scam where malicious actors secretly hijack a victim’s computer or device to mine cryptocurrencies without their knowledge or consent. This is typically done by injecting malicious code into websites or applications, allowing the attacker to utilize the victim’s computing resources for mining purposes.

How to Avoid Cryptojacking:

  • Use reputable antivirus and anti-malware software to detect and prevent cryptojacking attempts.
  • Keep your web browser and software up to date with the latest security patches.
  • Be cautious of websites or applications that consume excessive CPU power, as this could be a sign of cryptojacking.

6. Ransomware Attacks

Ransomware attacks are a form of cryptocurrency scam where cybercriminals gain unauthorized access to a victim’s computer or network and encrypt their files or data. The attackers then demand a ransom, usually payable in cryptocurrencies like Bitcoin, in exchange for a decryption key that will restore access to the victim’s files. Ransomware attacks can have devastating consequences, both for individuals and organizations.

How to Avoid Ransomware Attacks:

  • Regularly back up your important files and data to an offline or secure location. This will allow you to recover your data without paying a ransom in case of an attack.
  • Install and maintain reputable antivirus and anti-malware software on your devices to detect and prevent ransomware attacks.
  • Avoid opening email attachments or clicking on links from unknown or suspicious sources. Ransomware often spreads through malicious email attachments.
  • Ensure that your operating system and software applications are up to date with the latest security patches. Cybercriminals often target known vulnerabilities.
  • Avoid Paying Ransoms: Law enforcement agencies and cybersecurity experts generally advise against paying ransoms, as it encourages criminal activity. Instead, report the incident to the authorities and seek professional help to resolve the situation.
