1. Bitcoin investment schemes
In bitcoin investment schemes, scammers contact investors claiming to be seasoned “investment managers.” As part of the scheme, the so-called investment managers claim to have made millions investing in cryptocurrency and promise their victims that they will make money with investments.
To get started, the scammers request an upfront fee. Then, instead of making money, the thieves simply steal the upfront fees. The scammers may also request personal identification information, claiming it’s for transferring or depositing funds, and thus gain access to a person’s cryptocurrency.
Another type of investment scam involves using fake celebrity endorsements. Scammers take real photos and impose them on fake accounts, ads or articles to make it appear as though the celebrity is promoting a large financial gain from the investment. The sources for these claims appear to be legitimate, using reputable company names such as ABC or CBS with a professional-looking website and logos. However, the endorsement is fake.
2. Rug pull scams
Rug pull scams involve investment scammers “pumping up” a new project, nonfungible token (NFT) or coin to get funding. After the scammers get the money, they disappear with it. The coding for these investments prevents people from selling the bitcoin after purchase, so investors are left with a valueless investment.
A popular version of this scam was the Squid coin scam, named after the popular Netflix series Squid Game. Investors had to play to earn cryptocurrency: People would buy tokens for online games and earn more later to exchange for other cryptocurrencies. The price of the Squid token went from being worth 1 cent to about $90 per token.
Eventually, trading stopped and the money disappeared. The token value then reached zero as people attempted but failed to sell their tokens. The scammers made about $3 million from these investors.
Rug pull scams are also common for NFTs, which are one-of-a-kind digital assets.
3. Romance scams
Dating apps are no stranger to crypto scams. These scams involve relationships — typically long-distance and strictly online — where one party takes time to gain the other party’s trust. Over time, one party starts to convince the other to buy or give money in some form of cryptocurrency.
After getting the money, the dating scammer disappears. These scams are also referred to as “pig butchering scams.”
4. Phishing scams
scams have been around for some time but are still popular. Scammers send emails with malicious links to a fake website to gather personal details, such as cryptocurrency wallet key information.
Unlike passwords, users only get one unique private key to digital wallets. But if a private key is stolen, it is troublesome to change this key. Each key is unique to a wallet; so, to update this key, the person needs to create a new wallet.
To avoid phishing scams, never enter secure information from an email link. Always go directly to the site, no matter how legitimate the website or link appears.
5. Man-in-the-middle attack
When users log in to a cryptocurrency account in a public location, scammers can steal their private, sensitive information. A scammer can intercept any information sent over a public network, including passwords, cryptocurrency wallet keys and account information.
Anytime a user is logged in, a thief can gather this sensitive information by using the approach. This is done by intercepting Wi-Fi signals on trusted networks if they are in close proximity.
The best way to avoid these attacks is to block the man in the middle by using a virtual private network. The VPN encrypts all the data being transmitted, so thieves cannot access personal information and steal cryptocurrency.
6. Social media cryptocurrency giveaway scams
There are many fraudulent posts on social media outlets promising bitcoin giveaways. Some of these scams also include fake celebrity accounts promoting the giveaway to lure people in.
However, when someone clicks on the giveaway, they are taken to a fraudulent site asking for verification to receive the bitcoin. The verification process includes making a payment to prove the account is legitimate.
The victim can lose this payment — or, worse yet, click on a malicious link and have their personal information and cryptocurrency stolen.
7. Ponzi schemes
Ponzi schemes pay older investors with the proceeds from new ones. To get fresh investors, cryptocurrency scammers will lure new investors with bitcoin. It’s a scheme that runs in circles, since there are no legitimate investments; it is all about targeting new investors for money.
The main lure of a Ponzi scheme is the promise of huge profits with little risk. There are always risks with these investments, however, and there are no guaranteed returns.
8. Fake cryptocurrency exchanges
Scammers may lure investors in with promises of a great cryptocurrency exchange — maybe even some additional bitcoin. But in reality, there is no exchange and the investor does not know it’s fake until after they lose their deposit.
Stick to known crypto exchange markets — such as Coinbase, Crypto.com and Cash App — to avoid an unfamiliar exchange. Do some research and check industry sites for details about the exchange’s reputation and legitimacy before entering any personal information.
9. Employment offers and fraudulent employees
Scammers will also impersonate recruiters or job seekers to get access to cryptocurrency accounts. With this ploy, they offer an interesting job but require cryptocurrency as payment for job training.
There are also scams when hiring remote workers. For instance, North Korean IT freelancers are trying to capitalize on remote job opportunities by presenting impressive resumes and claiming to be U.S.-based. The U.S. Department of the Treasury issued a warning of this North Korean scam targeting cryptocurrency companies.
These IT freelancers seek projects involving virtual currency and use access for the currency exchanges. They then hack into the systems to raise money or steal information for the Democratic People’s Republic of Korea (DPRK). These workers also engage in other skilled IT work and use their knowledge to gain insider access to enable the DPRK’s malicious cyber attacks.
How to protect bitcoin and cryptocurrency
To protect against cryptocurrency scams, here are some of the common red flags:
- promises for large gains or double the investment;
- only accepting cryptocurrency as payment;
- contractual obligations;
- misspellings and grammatical errors in emails, social media posts or any other communication;
- manipulation tactics, such as extortion or blackmail;
- promises of free money;
- fake influencers or celebrity endorsements that seem out of place;
- minimal details about money movement and the investment; and
- several transactions in one day.
Protect digital wallets from scammers by practicing good digital security habits such as strong passwords, using only secured connections or VPNs and choosing safe storage. There are two types of wallets: digital and hardware. Digital wallets are hosted online and have a higher rate of getting hacked. Hardware wallets store information, such as the cryptocurrency wallet and keys, offline within a device.
Cryptocurrency is not insured by the Federal Deposit Insurance Corporation, so keeping it safe is vital. Never give wallet keys or access codes to anyone.
