Bitcoin’s decentralised nature and high value make it appealing not only to investors but also to scammers. These fraudsters use various tactics to exploit users, leading to millions in losses every year. Learning to recognise and avoid these scams can save you from significant financial and emotional stress. These scams range from fake wallet apps and phishing websites to Ponzi schemes, celebrity impersonations, and investment "advisors" who make bold promises of guaranteed returns. Understanding these tactics is essential, as Bitcoin transactions are irreversible and often lack the legal protections of traditional financial systems.
In this guide, we’ll break down the most common Bitcoin scams, from phishing attempts and fake exchanges to high-return “opportunities” that sound too good to be true. We’ll cover essential red flags—such as unsolicited offers, urgent requests for Bitcoin-only payments, and suspicious websites—as well as practical ways to protect yourself. These include double-checking URLs, securing your digital wallet with two-factor authentication, and verifying the legitimacy of any service or investment offer before transferring any funds.
Whether you’re new to Bitcoin or a seasoned investor, this guide will help you recognise and steer clear of these scams. By equipping yourself with knowledge and a cautious approach, you can avoid costly mistakes, keep your investments secure, and enjoy the benefits of Bitcoin safely.
The Surge of Bitcoin Scams
According to ASIC, investment scams are on the rise, with Bitcoin being a major target. In 2021 alone, Australians lost more than $700 million to investment fraud, with cryptocurrency-related scams accounting for a large portion of this figure. The Australian Securities and Investments Commission (ASIC) offers practical guidance to protect consumers from fraud, especially during heightened periods such as Scams Awareness Week.
Types of Common Bitcoin Scams
1. Phishing Scams
Phishing is a tactic where scammers create fake emails or websites that mimic legitimate Bitcoin exchanges or wallets. These emails or messages often urge users to click on a link to "verify their account" or "resolve an issue," leading them to a fake login page where scammers capture their credentials.
How to Avoid: Always double-check URLs, avoid clicking on unsolicited links, and never share your private keys or seed phrases.
2. Fake Exchanges and Wallets
Some scammers establish fake exchanges and wallet apps that appear legitimate. These may offer attractive bonuses or low fees to entice users. After deposits are made, users often find themselves unable to withdraw funds or face high hidden fees.
How to Avoid: Stick to reputable, well-reviewed exchanges, verify app legitimacy before downloading, and avoid exchanges that push you to deposit funds quickly.
3. Old-School Scams Adapted to Bitcoin
Traditional scams like fake tax or “Nigerian prince” scams have found a new home in Bitcoin. Scammers may call, email, or message claiming to be from the tax office, threatening legal action unless a Bitcoin payment is made.
How to Avoid: Be cautious of unsolicited contact, especially calls or emails asking for payments. Verify claims by contacting institutions directly using official contact information. Don't give out personal information.
4. Fraudulent ICOs (Initial Coin Offerings)
ICOs offer investors the chance to buy into new projects early. Unfortunately, scammers use fake ICOs to lure in funds and then disappear with investors' money.
How to Avoid: Before investing, research the ICO team, their whitepaper, and reviews from credible sources.
5. Bitcoin Blackmail Scams
Scammers may send emails claiming to have hacked your computer, threatening to release compromising information unless you pay them in Bitcoin. These emails often include instructions for purchasing and sending Bitcoin.
How to Avoid: Ignore these emails and do not send funds. To add security, use a VPN and ensure your devices are protected with strong passwords.
6. Celebrity Impersonation Giveaway Scams
Scammers impersonate celebrities on social media, claiming to give away Bitcoin as long as you send some first. They promise to “double” your Bitcoin but instead disappear with your funds.
How to Avoid: Treat any Bitcoin giveaway, especially on social media, as suspicious. Verify accounts carefully and use blockchain explorers to check addresses.
7. Ponzi or Pyramid Schemes
Ponzi schemes lure investors with promises of high returns. Initial investors receive “payouts” from the funds of newer investors, creating an illusion of profitability until the scheme collapses.
How to Avoid: Be wary of investments that guarantee returns or encourage you to recruit others to increase your profits.
8. Rug Pulls and Exit Scams
In rug pulls, scammers create a project, attract funds, and then shut down the project, taking the money with them. This is especially common in DeFi (Decentralised Finance) projects.
How to Avoid: Avoid projects where private keys are controlled by a single developer, seek projects that have undergone a third-party audit, and be cautious of new, unverified projects.
9. Malware
Bitcoin-specific malware can infect your device, monitoring for wallet addresses or even directly stealing funds from your wallet.
How to Avoid: Regularly update your antivirus software, only download software from reputable sources, and avoid suspicious email attachments or downloads.
10. Mining Scams
Cloud mining scams promise returns from Bitcoin mining but often take funds without providing any return. Many are fronts for Ponzi schemes, while others hide fees or charge inflated prices.
How to Avoid: Avoid cloud mining schemes, as even legitimate ones are often not profitable. Instead, consider buying Bitcoin directly if you’re interested in investing.
11. Pump-and-Dump Schemes
Pump-and-dump schemes involve artificially inflating the price of a low-value cryptocurrency by promoting it to a large audience. After the price rises, scammers sell their holdings, leaving new buyers with significant losses.
How to Avoid: Be cautious of sudden surges in low-value tokens and avoid FOMO (fear of missing out) impulses. Conduct research before buying any new coin.
ASIC’s Top 10 Warning Signs of Bitcoin Scams
ASIC has compiled a list of common indicators of Bitcoin scams to help consumers avoid becoming victims:
Unsolicited Contact: Be cautious of unexpected messages or calls offering investment opportunities.
Fake Celebrity Endorsements: Scammers often impersonate well-known figures to add credibility often with AI generated videos.
Romantic Interest Requests for Bitcoin: Online “partners” or friends requesting Bitcoin are typically scammers.
Pressure to Transfer Funds: Legitimate platforms won’t pressure you to transfer Bitcoin urgently.
Bitcoin-Only Payments for Services: Legitimate services rarely demand Bitcoin as the only payment method.
Apps Not Listed on Official Stores: Avoid unlisted apps, as they may be fraudulent.
Locked Funds with Added Fees: Scammers may require extra payments to “unlock” your money.
Guaranteed High Returns: Returns in Bitcoin are never guaranteed.
Strange Tokens in Your Wallet: Be cautious of unexpected tokens, as they may be phishing attempts.
Withholding for ‘Tax Purposes’: Legitimate entities won’t withhold funds for taxes. If they do, it’s a scam.
Tips to Protect Yourself from Bitcoin Scams
1. Do Thorough Research
Before using a platform, check if it’s registered with AUSTRAC in Australia, and review its history online. Reliable sites should have clear information and positive feedback.
2. Verify Identities and Endorsements
Look up key figures associated with the platform, verify any claimed endorsements, and use reputable news sites or industry sources for verification.
3. Enable Security Features
Use two-factor authentication (2FA) and secure your private keys with hardware wallets or cold storage to protect against theft.
4. Question Unusual Payment Requests
Be cautious if a person or company insists on payment in Bitcoin. Avoid job offers requiring Bitcoin purchases or requests from online acquaintances, as these are often scams.
5. Stick with Reputable Apps and Platforms
Only download Bitcoin apps from official app stores, and check reviews for security issues. Be cautious of new apps or browser extensions that are not widely reviewed.
6. Stay Informed About New Scam Tactics
As scammers develop new methods, keep up-to-date on common scam tactics and educate yourself on Bitcoin security best practices.
What to Do If You’ve Been Scammed
Cease Communication: Immediately cut off all contact with the scammer.
Notify Your Financial Institution: Report the incident to your bank if the funds were transferred from your account.
Report the Scam: File a report with ASIC, Scamwatch, or ReportCyber. These agencies provide resources for reporting and investigating scams.
Warn Your Social Network: Inform friends, family, and colleagues to help prevent follow-up fraud.
Consider Support Services: Scams can be distressing. Support organisations such as Lifeline or Beyond Blue offer emotional support for affected individuals.
Final Thoughts
Bitcoin can be a valuable investment, but it requires vigilance to navigate safely. By following ASIC’s guidelines, understanding common scam tactics, and remaining cautious, you can protect yourself from fraud. Always remember: if an investment sounds too good to be true, it probably is. Educate yourself, stay alert, and only engage with well-vetted platforms to enjoy Bitcoin’s benefits with confidence.
