Most Common Bitcoin Scams and How to Spot Them Before You Lose Your Money

Bitcoin scams are getting more sophisticated all the time. Fraudulent websites look like real investment platforms, fake advisors come across as professional, and ads featuring celebrities can now be generated using artificial intelligence. The biggest warning sign is often not a technical flaw but a promise of extraordinary returns, time pressure, and a request that the investor send money or crypto to an address dictated by a stranger.

Scammers usually don't try to break into the Bitcoin network itself. They target the person: their trust, fear, or desire for a quick profit. Once a victim sends bitcoin to the perpetrator's wallet, the transaction generally cannot simply be reversed the way a card payment can. It is precisely the speed, global reach, and practical irreversibility of crypto transfers that make bitcoin an attractive tool for scammers.

The scale of the problem is growing. According to the analytics firm Chainalysis, scammers extracted an estimated $17 billion through cryptocurrencies in 2025. The number of impersonation scams involving a person or institution rose sharply year over year, and AI-powered scams were on average 4.5 times more profitable than traditional scam campaigns, according to the analysis.

Fake Investment Platforms Show Profits That Don't Exist

Among the most common bitcoin scams are fake investment platforms. Victims often find them through a social media ad, an article mimicking a trusted media outlet, or a video in which a supposedly well-known figure recommends investing in bitcoin.

After entering a phone number, an "investment advisor" usually calls. They offer to help set up an account and persuade the prospect to send a first, relatively small amount. A growing balance then starts appearing on the web platform. The charts, numbers, and reported trades, however, may have nothing to do with the real market.

The scammer gradually tries to convince the victim to invest more, use up all their savings, or even take out a loan. The problem surfaces the moment the investor wants to withdraw the money. The platform starts demanding payment of a tax, an activation fee, insurance, a commission, or a supposed anti-money-laundering fee. Even after paying it, no withdrawal ever arrives.

In March 2026, the Czech National Bank issued a warning about fraudulent platforms offering AI-powered cryptocurrency trading. A typical feature of these schemes is the rapid switching of names, brands, and web addresses, designed to make identification and any regulatory intervention more difficult.

Scammers may also hijack the identity of real companies, well-known figures, or regulators. They create a fake authorization, use the logo of a trusted institution, and add fabricated reviews to the website. A professional-looking site alone is therefore not proof that an investment platform actually exists.

No legitimate bitcoin investment can guarantee a profit. Returns depend on how the market price develops, and no advisor can reliably guarantee that an investor will earn a specific percentage daily, weekly, or monthly.

An "AI Trading Bot" May Just Be a New Name for an Old Scam

With the rise of artificial intelligence, it is above all the marketing of fraudulent schemes that has changed. Instead of an ordinary investment platform, the pitch now often promotes an automated AI system that supposedly can predict bitcoin's price, trade risk-free, and generate stable passive income.

The mere use of artificial intelligence, however, does not mean a service is trustworthy. Scammers use the "AI" label mainly because it sounds technologically advanced, and an ordinary user cannot easily verify how the system actually works.

What should raise particular suspicion is the combination of artificial intelligence, a guaranteed return, and a claim that the offer is only available for a few hours. A serious provider will not pressure a potential client into an immediate decision or claim that the risk of loss is practically nonexistent.

Deepfake Videos Exploit Celebrities and Media Outlets

Fraudulent ads can look like a TV news segment, an article from a well-known news outlet, or an interview with a politician, entrepreneur, or celebrity. Using deepfake technology, perpetrators can create a video in which a well-known figure supposedly recommends a specific platform or describes how much money they made through it.

Warning signs can include unnatural lip movements, an odd voice intonation, errors in the outlet's name, or a web address that differs from the original by a single character. Increasingly convincing deepfake content, however, may not be identifiable from the visuals alone.

What matters most is therefore the offer itself. If a video promises fast, guaranteed earnings, asks for a phone number, or redirects the user to an unknown investment site, it is very likely a scam.

A Romantic Relationship Can Turn Into an Investment Trap

The so-called romance investment scam, sometimes called "pig butchering," is among the most dangerous scams precisely because at first it may not resemble an investment offer at all.

The perpetrator contacts the victim through a dating app, social media, or a seemingly random message. Over several weeks or months, they build the victim's trust, take an interest in their life, and create the impression of a friendly or romantic relationship. Only later do they mention that they make money trading bitcoin and offer to show the victim how.

A link to a fake platform follows. Scammers sometimes let the victim withdraw a small first profit to confirm the system's credibility. Once the victim sends a larger amount, withdrawals stop and the supposed partner starts demanding further deposits.

A Fake Banker or Police Officer Sends the Victim to a Bitcoin ATM

Another widespread scenario doesn't start with the promise of earnings but with fear. The caller identifies themselves as a bank employee, a police officer, or a security officer. They claim the client's account has been hacked, that someone is trying to take out a loan in their name, or that their savings are in immediate danger.

The supposed solution is to withdraw the money and deposit it into a bitcoin ATM. The scammer sends a QR code and claims it will transfer the money to a safe wallet. In reality, it is an address controlled by the perpetrator.

Scammers can also spoof a bank's or other institution's phone number, a technique known as spoofing. The number shown on the display is therefore not proof that the bank or police are really calling.

Any such call should be ended immediately, and the situation verified independently. You should call the bank using the phone number listed on its official website or on your payment card, not a contact provided by the caller.

Phishing Steals Login Credentials and Entire Bitcoin Wallets

A phishing attack tries to get the user to enter their login credentials on a fake page. The message may look like a crypto exchange's alert about a suspicious login, a need to verify the account, or a time-limited security check.

The link, however, leads to a website whose address differs from the original by, say, a single letter. Once the user enters the password and authorization code, the scammer can gain access to their actual account.

Even more serious is a request to enter the seed, the recovery phrase for a crypto wallet. A seed usually consists of a series of 12 or 24 words and represents the master key to the stored funds. Whoever obtains it can restore the wallet on their own device and send the bitcoin elsewhere.

Legitimate customer support, an exchange, or a hardware wallet manufacturer never needs to know a user's recovery phrase. A seed is never entered into a form sent by email, never given out over the phone, and never sent to a support representative. Being asked for it is a near-certain sign of a scam.

Fake Customer Support Lurks on Social Media

A user whose exchange withdrawal isn't working, or who has a wallet problem, often looks for help on social media. Scammers actively monitor these posts and quickly respond from an account mimicking official support.

The fake support agent offers a solution through a private message. They then ask for login credentials, the seed, installation of a program, linking the wallet to an unknown site, or sending bitcoin to "verify the address."

Real customer support will never ask you to transfer cryptocurrency or hand over a private key. It's safer to contact support directly through the service's official app or website, typing the address in yourself.

Remote Access Lets a Scammer Take Over Your Computer

A fake investment advisor sometimes offers to help a client buy bitcoin. They ask the client to install remote-access software, such as AnyDesk or TeamViewer.

Such software is legitimate, but in a scammer's hands it can let them watch the victim log into online banking, manipulate transactions, or take control of the device. The perpetrator can hide part of the screen, alter the displayed information, and transfer money at the same time.

In connection with fraudulent crypto investments, the Czech Police therefore recommend never granting remote access to your computer to a stranger, and never handing over copies of personal documents or login credentials to unknown people.

Professional-sounding communication and an apparently functioning investment account are no guarantee that the money actually exists. Police have also described a case in which a woman, after installing a remote-access app, transferred nearly 1.5 million crowns to foreign accounts but never received the promised investment returns or her money back.

A Second Scam Arrives Offering to Recover the Bitcoin

Shortly after losing money, a scam victim can become the target of a second attack. A supposed law firm, investigator, hacker, or crypto-recovery company gets in touch, claiming to have tracked down the perpetrator and to be able to recover the bitcoin.

The condition is paying a deposit, a court fee, a tax, or an amount needed to "unlock" the recovered wallet. Payment is followed by further demands, but the money is never returned.

How to Spot a Bitcoin Scam Before Sending Any Money

Suspicion should be raised by any offer that combines a guaranteed return, time pressure, and active phone-based persuasion. Equally dangerous is a request to install remote access, to send a copy of your documents to a stranger, to share an authorization code, or to transfer bitcoin to an address supplied by an "advisor."

A company's trustworthiness cannot be verified from its website, reviews, or a document bearing a regulator's logo alone. Scammers can build professional-looking sites, fake reviews, and forged licenses.

A company's identity and authorization must be verified directly in the list of regulated and registered entities of the Czech National Bank, which contains entities authorized or registered to operate on the Czech financial market.

As of July 1, 2026, crypto-asset services in the European Union may only be provided by companies holding the relevant authorization under the MiCA regulation or by authorized financial institutions. The Czech National Bank therefore recommends that clients verify a provider's authorization in the CNB or ESMA register before using its services, and throughout the duration of the contractual relationship.
