How to Spot Bitcoin Scams: The Most Common Tricks

You can spot a bitcoin scam by three things: someone promises fixed or high returns, someone puts you under time pressure, and someone wants your seed phrase, access to your device or a payment to "unlock" something. If any one of these applies, it is very likely a scam. A bitcoin payment cannot be reversed.

Why bitcoin scams work so well

Your bank can sometimes claw back a bank transfer. A bitcoin payment, never. As soon as it is in the next block, the money belongs to whoever holds the key to the receiving address. There is no hotline that can stop it.

This property protects you when you hold your coins yourself. Scammers exploit it: they get you to make the payment yourself. No hack is needed at all.

The sums are large. The FBI counted around $11.4 billion in losses from cryptocurrency fraud in 2025, of which around $7.2 billion came from fake investment offers alone. Victims over 60 lost around $4.4 billion. The analytics firm Chainalysis estimates that scammers took in at least $14 billion in cryptocurrency worldwide in 2025, probably more than $17 billion. There is no separate figure for Germany, Austria and Switzerland; the tricks are the same.

The four warning signs almost every scam has

The stories change, the pattern stays. Check every offer and every message for these four points:

1. Promised returns. Fixed, high or "guaranteed". Bitcoin fluctuates, and no one can promise its price.
2. Time pressure. "Today only", "your account will be blocked", "the police are already on their way". Pressure is meant to stop you from thinking or asking someone.
3. The contact came from the other side. A call, a WhatsApp message, someone you met on a dating app, an ad featuring a celebrity. Legitimate providers don't contact you out of the blue.
4. An unusual route. Entering your seed, installing a remote-access app, paying to an address someone sends you, feeding cash into a bitcoin ATM.

One warning sign is enough to stop. Two or more, and it is almost certainly a scam.

The most common scams at a glance

Scam 1: The fake trading platform

This is the most expensive scam. It starts with an ad ("Earn passively with bitcoin") or a call. A friendly "broker" helps you with a small first deposit, often €250. On the platform your account grows fast, and you pay in more.

When you want to withdraw, a hurdle appears: a tax, an "unlock fee", an insurance. If you pay it, the next one follows. The gains never existed; the platform is just a website that displays numbers.

Often the "broker" also asks you to install a remote-access app such as AnyDesk or TeamViewer to "help". With it he sees your screen and can operate your online banking or your wallet.

Scam 2: Romance scams and "pig butchering"

Someone messages you, seemingly at random, on Instagram, LinkedIn, a dating app or with a "wrong number" on WhatsApp. You chat for weeks, and trust or a relationship develops. At some point they tell you how they earn money with bitcoin and show you "their" platform.

The name "pig butchering" describes the method: the victim is first "fattened up" with attention and small real gains, then slaughtered. Behind many of these contacts are organised gangs, often in Southeast Asia, whose workers are themselves forced to write the messages.

A clear sign: the person never wants to talk spontaneously on video, or the video seems odd. And someone who loves you doesn't need your savings on a platform only they know about.

Scam 3: Phishing and fake support

You get an email, a text or even a letter: your wallet must be "verified", there is a security problem, or your exchange will block your account. A link leads to a page that looks real and asks for your seed phrase or password.

After a data leak at the hardware wallet maker Ledger in 2020, customers received exactly this kind of mail, some with their name and address. Others look for help in forums or on X and immediately get a message from "support" that is really a scammer.

The rule is simple: you only ever enter your seed phrase into your own device, and only when you are restoring a wallet yourself. Never into a website, never into a form, never for someone else. How to store it safely is in the custody guide.

Scam 4: Fake wallet apps and devices

Copies of well-known wallets keep appearing in app stores. They seem to work normally but send the seed you create or enter to the scammers. Often a paid search ad sits above the real result.

How to protect yourself:

• Download wallet apps only via the link on the manufacturer's website, which you type in yourself.
• Buy hardware wallets directly from the manufacturer or an official reseller, never second-hand.
• If a device comes with a pre-filled seed, it has been tampered with. A genuine device generates the seed itself during first setup.

A related trick is malware that swaps a copied bitcoin address for the attacker's. So before every payment, compare the address on your hardware wallet's display, at least the beginning and the end.

Scam 5: Celebrity ads, deepfakes and doublers

An article styled like a major newspaper reports that a well-known TV personality got rich with a "bitcoin robot". Or a video shows an entrepreneur promising to send back double any amount you send. Both are fake, often generated with artificial intelligence.

Behind the link there is usually one of the fake trading platforms from scam 1, or an address you are supposed to pay directly. No celebrity gives bitcoin away to strangers, and no program earns safe money "automatically".

Scam 6: Shock calls and bitcoin ATMs

Someone calls pretending to be the police, your bank or a public authority. Your account has been hacked, or a family member is in trouble. To "secure" your money, you are told to withdraw it and send it via a bitcoin ATM to an address given to you as a QR code.

No police force and no bank ever asks you to exchange money for bitcoin or take it to an ATM. In the US, according to the FBI, victims lost around $389 million through such ATMs in 2025. Hang up and call the organisation on a number you look up yourself.

Scam 7: Cloud mining, bots and yield pools

You are not asked to buy bitcoin, but to rent computing power, subscribe to a trading bot or put coins into a pool that pays fixed interest. At first small payouts arrive, often from later customers' money. Then they stall.

Real mining is a thin-margin business: electricity price, hardware and difficulty determine the yield, and it fluctuates. How it works is explained in Bitcoin mining explained. You can calculate what a machine realistically earns yourself:

If an offer is far above what the calculator shows, something is wrong with the offer, not with the calculator.

Scam 8: The recovery scam

Anyone who has been scammed once often ends up on a list. A few weeks later a "law firm", an "authority" or a "blockchain investigator" gets in touch: they have traced your money and can get it back, for an upfront fee.

This is the same scam a second time, sometimes by the same perpetrators. Real investigations go through the police and cost you nothing. Reputable lawyers don't promise success and don't ask for payment in bitcoin.

How to check any offer in five steps

1. Check the regulator. Look up the provider in the BaFin company database, with the FMA or on the FINMA warning list. No entry, no deposit.
2. Search the name. Enter the provider's name together with "scam" or "reviews" into a search engine. Also check how long the domain has existed. Scam sites are often only a few weeks old.
3. Check the return. Is more promised than bitcoin grows along its trend, or is a fixed figure named? Then it is not a bitcoin business.
4. Rule out seed and remote access. If someone wants your words, a photo of them or a remote-access app, the conversation is over.
5. Sleep on it and ask someone. Real offers will still be there tomorrow. Tell someone you trust about it. That is exactly what scammers want to prevent.

Where to buy bitcoin safely and how to compare providers is shown in the guide to buying bitcoin in the DACH region. Why even a real, regulated exchange is no place to store your coins is shown by the exchange collapses from Mt. Gox to FTX.

Bitcoin scam spotted, but too late: what to do now

Don't be ashamed. These scams are built by professionals, and they hit doctors, engineers and bankers just the same. What matters is what you do in the next few hours:

1. Stop paying immediately. No "fee", no "tax", no final amount. It will not bring the money back.
2. Cut off access. Uninstall the remote-access app, change the passwords for email, bank and exchange, turn on two-factor authentication. If someone has seen your seed, move the remaining coins immediately to a new wallet with a new seed.
3. Secure everything. Screenshots of chats, website and account balances, the bitcoin addresses, transaction IDs and transfer receipts.
4. Inform your bank and exchange. A transfer in euros or francs can sometimes still be stopped. If the money went through a regulated exchange, it can freeze the other side's account when the police ask.
5. Report it to the police. In Germany at any police station or online via your federal state's Onlinewache (online police station), in Austria to the police, in Switzerland to the cantonal police. In Switzerland, the National Cyber Security Centre (NCSC) also accepts reports.

And if someone then contacts you offering to get the money back: see scam 8.
