In this lesson you will learn to:
- Recognise the most common scam patterns.
- Explain why blockchain transfers are hard to reverse.
- Know where to report fraud.
Why scammers love this topic
Three features of public blockchains attract fraud. Transfers are usually irreversible: there is no bank to call back a payment. Many people are new to the technology and unsure what is normal. And the topic is surrounded by stories of sudden wealth, which scammers use as bait. Regulators in Europe, the UK and the US repeatedly list crypto-related fraud among the most common consumer scams.
Five patterns to recognise
1. The promise
Any message that promises steady, high or certain gains is the clearest warning sign. Real technology education does not promise anything about value. Fake platforms often show impressive numbers on a dashboard to encourage larger transfers — numbers that cannot be withdrawn.
2. The impersonator
Fake support staff, fake celebrities in edited videos, fake officials. They contact you first, often through social media or messaging apps, and create urgency: "your account is at risk", "verify now".
3. The phishing copy
Look-alike websites and apps designed to capture passwords or recovery phrases. The address may differ by a single letter. Sponsored search results and links in messages are common routes.
4. The slow friendship
Sometimes called "pig butchering", this pattern begins with a friendly conversation or romance that lasts weeks before turning to "an opportunity". It is designed to build trust before asking for anything.
5. The recovery service
After a loss, victims are often approached by people offering to recover funds for an upfront fee. This is almost always a second scam targeting the same person.
Simple habits that help
- Never share keys or a recovery phrase — the rule from lessons 5.1 and 5.2.
- Pause whenever someone creates urgency. A real opportunity does not vanish in ten minutes.
- Verify identities through official channels you find yourself, not through the contact details in the message.
- Be wary of anyone who contacts you first about crypto.
- Talk it over with someone you trust before acting. Scammers rely on isolation.
If it happens
Stop contact, keep evidence, and report it to the police and your national fraud reporting service. The safety page lists official resources. Being targeted is not a sign of foolishness — these operations are professional and well organised.
Key takeaways
- Irreversible transfers, inexperienced users and hype make crypto attractive to scammers.
- Promises of gains, urgency and unsolicited contact are the strongest warning signs.
- Phishing copies and "recovery services" target people at their most vulnerable.
- Pausing, verifying independently and talking to someone you trust prevent most losses.
