The rise of blockchain technology and cryptocurrencies has sparked a wave of innovation, transforming how people invest, transact, and think about finance. However, alongside this rapid growth comes a darker side: an increasing number of scams targeting both new and experienced users. While awareness of crypto fraud has improved over the years, deceptive schemes continue to evolve and thrive. Understanding the most common types of cryptocurrency scams—and how to avoid them—is essential for protecting your digital assets.
This guide outlines key fraud patterns, warning signs, and practical prevention strategies to help you navigate the crypto space safely.
Major Types of Cryptocurrency Scams
1. Fake ICOs (Initial Coin Offerings)
One of the most widespread scams during the 2017 crypto boom was fraudulent ICOs. Research indicates that up to 80% of ICOs launched in 2017 were scams. A notorious example is Confido, which raised $375,000 before its team vanished overnight. The token’s value plummeted from $0.06 to less than $0.01 within hours.
Another high-profile case was Centra Tech, which raised $32 million with celebrity endorsements from Floyd Mayweather and DJ Khaled. In 2018, two of its founders were arrested for fraud. Their tokens collapsed immediately after the news broke.
Some fake ICOs go as far as fabricating entire teams—using stolen photos of real people or even celebrities like Ryan Gosling. Always verify team members through reverse image searches and professional profiles like LinkedIn.

2. Phony Giveaways
Be wary of social media posts—especially on platforms like Twitter, Telegram, or Facebook—claiming that influencers like Vitalik Buterin or Andreas Antonopoulos are giving away free cryptocurrency. Messages such as "Send 1 ETH and receive 10 ETH in return!" are always scams.
Cryptocurrency has real value—no legitimate developer or investor will double your funds for free. These scams often use hacked accounts or fake profiles to appear credible.
3. Clone Websites
Scammers create near-identical copies of legitimate exchange or project websites to steal login credentials and funds. These clone sites use URLs with subtle differences—like replacing “o” with “0” or “l” with “i”—to trick users.
For example, instead of myetherwallet.com, a phishing site might use myeth3rwallet.com. Always double-check URLs before logging in or making transactions.
4. Malicious Ads
Even search engines like Google have hosted fake ads leading to cloned versions of popular exchanges or wallet services. Users have reported encountering counterfeit Trezor ads on Reddit and fake Binance ads on Google.
To stay safe:
- Bookmark official websites.
- Avoid clicking on paid ads for crypto services.
- Use browser extensions like MetaMask or known anti-phishing tools.
👉 Discover secure ways to access trusted crypto platforms without falling for fake ads.
5. DNS Hijacking
In a DNS attack, hackers redirect traffic from a legitimate website to a fraudulent one by tampering with domain name system records. Even if you're using a saved bookmark, you could still be sent to a fake version of MyEtherWallet or MyCrypto.
Warning signs include:
- SSL certificate mismatches.
- Browser security warnings.
- Unexpected login pages.
A strong defense is running wallet interfaces locally (offline) on your computer.
6. Phishing Emails
Phishing emails mimic official communications from ICOs, exchanges, or wallet providers. They often contain links to fake login pages designed to capture your credentials.
These scams spike during active token sales when investors are expecting updates. Never click links in unsolicited emails—even if they appear legitimate.
7. Fake Support Teams
Scammers pose as customer support agents via social media or messaging apps, offering help with account recovery or transactions. They may ask for your private key, seed phrase, or login details—which no real support team will ever request.
Always contact support only through verified official channels.
8. Fake Exchanges and Apps
With over 200 exchanges listed on tracking sites like CoinMarketCap, it's easy for fraudulent platforms to blend in. Fake exchanges like BitKRX (exposed in 2017) mimic real ones but disappear after collecting user deposits.
Similarly, malicious mobile apps impersonate wallets like Trust Wallet or MetaMask. Only download apps from official app stores and verify developer names.
9. Cloud Mining Scams
Cloud mining allows users to rent mining power without owning hardware—making it attractive but also vulnerable to fraud. Scams like MiningMax promised high returns in exchange for large investments, operating as Ponzi schemes.
Red flags:
- Guaranteed daily returns.
- Referral bonuses based on recruitment.
- Lack of transparency about mining facilities.
Legitimate cloud mining exists but requires due diligence.
10. Ponzi Schemes, Pyramid & MLM Scams
Ponzi schemes pay early investors with money from new participants. Bitconnect is the most infamous example—peaking at a $2 billion valuation before collapsing within 24 hours, wiping out nearly all investor value.
These schemes often feature:
- Tiered referral systems.
- Pressure to recruit others.
- Unrealistic profit claims.
If it sounds too good to be true, it probably is.
11. Malware Attacks
Malicious software targets crypto users in two main ways:
- Wallet-stealing malware that captures private keys.
- Cryptojacking, where hackers use your device’s resources to mine cryptocurrency without consent.
Symptoms include:
- High CPU/GPU usage.
- Overheating devices.
- Sluggish performance.
Use trusted antivirus software and avoid installing unverified browser extensions.
12. Fake Mining Pools & OTC Scams
Scammers create fake mining pools via Telegram or Discord, promising rewards for contributing ETH to upcoming ICOs. Once you send funds, they disappear.
OTC (over-the-counter) scams involve direct trades where one party sends money but receives nothing in return. Always use escrow services or trusted intermediaries—but verify their legitimacy first.
13. Pump-and-Dump Schemes
In these manipulative schemes, coordinated groups inflate the price of low-market-cap coins through artificial trading volume, then sell at the peak. Latecomers suffer heavy losses.
These groups often operate in private chat rooms and may promise exclusive access—another red flag.
14. SIM Swap Attacks
Attackers impersonate you to your mobile carrier and transfer your phone number to a new SIM card. With control of your number, they can bypass SMS-based two-factor authentication (2FA) and access email and exchange accounts.
Protect yourself by:
- Using authenticator apps (e.g., Google Authenticator).
- Enabling hardware-based 2FA.
- Contacting your carrier about SIM lock protection.
Key Warning Signs to Watch For
| Red Flag | What It Means |
|---|---|
| Guaranteed high returns | No investment is risk-free; extreme promises signal fraud. |
| Must refer others | Legitimate projects don’t require recruitment for payouts. |
| Requests for private keys | Never share your seed phrase or private key with anyone. |
| Anonymous team | Lack of verifiable team info increases scam risk. |
| Past fraudulent history | If a project or person scammed before, assume they will again. |
Frequently Asked Questions (FAQ)
Q: Can I recover funds lost to a crypto scam?
A: Unfortunately, most crypto transactions are irreversible. Once funds are sent to a scammer’s wallet, recovery is nearly impossible without law enforcement intervention.
Q: Are all new crypto projects scams?
A: No—many innovative and legitimate projects launch regularly. The key is thorough research: check the team, audit reports, community feedback, and code transparency.
Q: Is cold storage safer than hot wallets?
A: Yes. Hardware wallets (cold storage) keep private keys offline, significantly reducing exposure to online threats like hacking and malware.
Q: How can I verify an official website?
A: Use bookmarks from trusted sources, check SSL certificates, look for community verification on forums like Reddit or Twitter, and cross-reference URLs across multiple platforms.
Q: Should I trust celebrity-endorsed crypto projects?
A: Not automatically. Many celebrities have promoted scams unknowingly. Focus on the project fundamentals—not the promoter.
Q: What’s the safest way to participate in an ICO?
A: Use official links from the project’s verified website, enable multi-factor authentication, avoid sharing personal details unnecessarily, and never send funds to unverified addresses.
