Common Scams and How to Avoid Them

If it sounds too good to be true...

Bitcoin's permissionlessness is a feature. Anyone can use it without asking permission. Unfortunately, that includes scammers.

The crypto space is infested with fraud. People lose millions daily to schemes that could easily be avoided. Let's make sure you're not one of them.

The Golden Rule

If someone promises guaranteed returns, they're lying.

No one can guarantee bitcoin returns. Bitcoin's price is volatile and unpredictable. Anyone claiming otherwise is running a scam.

This applies to:

Scam Type 1: Phishing

How it works:
You receive an email, message, or see an ad that looks like it's from a legitimate service (exchange, wallet, etc.). You click a link, enter your credentials or seed phrase, and the scammer takes everything.

Examples:

How to avoid:

Scam Type 2: Giveaway Scams

How it works:
"Send 0.1 BTC and receive 0.2 BTC back!" Often impersonating celebrities or companies.

This is always a scam. No one is giving away free bitcoin. Not Elon Musk. Not Coinbase. Not anyone.

How to avoid:

Scam Type 3: Ponzi/Pyramid Schemes

How it works:
You invest, receive returns from new investors' money, recruit others who do the same. Eventually, the scheme collapses and most people lose everything.

How to avoid:

Scam Type 4: Fake Exchanges/Services

How it works:
You deposit bitcoin on what looks like a legitimate exchange or lending platform. You see impressive returns on screen. When you try to withdraw, the money isn't there.

Famous examples:

How to avoid:

Scam Type 5: Romance/Social Engineering

How it works:
Someone builds a relationship with you (romantic, friendship, mentorship). They introduce you to a "great investment opportunity." You send money. They disappear.

This is increasingly common and targets people across all demographics. It's sometimes called "pig butchering"—fattening up the victim before the slaughter.

How to avoid:

Scam Type 6: Impersonation

How it works:
Scammers pose as customer support, government officials, or other authority figures. They create urgency and demand you send bitcoin or share credentials.

Examples:

How to avoid:

Scam Type 7: Rug Pulls (Altcoins)

How it works:
A new token launches with hype. Price pumps. Creators sell their holdings or drain the liquidity pool. Price crashes to zero.

This is extremely common in altcoins, DeFi, and NFT projects.

How to avoid:

The "I'll Never Fall for That" Problem

Everyone thinks they're too smart to get scammed. Yet billions are lost annually.

Scammers are sophisticated. They exploit:

Stay humble. Stay skeptical. Verify everything.

Recovery Scams

Lost crypto to a scam? Scammers know this and run "recovery" scams:

These are also scams. Once bitcoin is sent, it cannot be recovered without the cooperation of the recipient. No service can magically retrieve it.

Remember

No one can recover stolen bitcoin. Anyone who claims they can is trying to scam you twice.

Lesson Summary

  • If it promises guaranteed returns, it's a scam
  • Never share your seed phrase with anyone for any reason
  • No one legitimate is giving away free bitcoin
  • Verify everything independently—don't trust links in messages
  • Test withdrawals before depositing significant amounts
  • Be skeptical of relationships that turn to investment advice
  • Focus on Bitcoin to avoid altcoin rug pulls
  • "Recovery services" for lost crypto are also scams
