The Crypto Scam Landscape
The Scale of the Problem
- $14 billion lost to crypto scams in 2021
- $3.5 billion stolen in 2022
- 46,000+ people report crypto scams annually (USA alone)
- 95% of new tokens are scams or fail
- Average loss: $2,600 per victim
Why Crypto Scams Are So Common
- Irreversible: Crypto transactions can't be reversed
- Anonymous: Scammers hard to trace
- Unregulated: Less protection than traditional finance
- Complex: Technical nature confuses victims
- FOMO: Fear of missing out makes people careless
- Greed: Promise of quick riches clouds judgment
Common Cryptocurrency Scams
1. Rug Pulls
What: Developers abandon project and steal all funds
How it works:
- Create new token with hype marketing
- Build liquidity pool on DEX
- Price pumps as people buy
- Developers remove all liquidity and disappear
- Token becomes worthless
Famous Example: Squid Game token - $3.3M stolen in 2021
Red Flags: Anonymous team, locked liquidity claims, unsustainable APYs
2. Phishing Attacks
What: Fake websites/emails steal your login credentials or seed phrase
Common Tactics:
- Fake exchange websites (Coinbse.com instead of Coinbase.com)
- Emails claiming "urgent security issue"
- Fake wallet apps in app stores
- Discord/Telegram DMs with "support" links
- Fake MetaMask pop-ups
Result: Scammers access your wallet and drain funds
Prevention: Always verify URLs, never share seed phrase, bookmark real sites
3. Ponzi/Pyramid Schemes
What: Pay early investors with new investors' money (unsustainable)
How it works:
- Promise guaranteed high returns (e.g., 1% daily)
- Pay early investors with new investors' deposits
- Encourage recruiting for bonuses (pyramid)
- Eventually collapse when no new investors
Famous Example: BitConnect - $2.4B scam, collapsed 2018
Red Flags: Guaranteed returns, recruitment bonuses, vague business model
4. Fake Exchanges
What: Websites that look like real exchanges but steal deposits
How it works:
- Create professional-looking exchange website
- Advertise on social media, Google ads
- Users deposit crypto
- Can't withdraw - site eventually disappears
Prevention: Only use well-known exchanges, verify URLs carefully
5. Fake Giveaways
What: "Send 1 ETH, get 2 ETH back" scams
Common Tactics:
- Fake Elon Musk/Vitalik Buterin Twitter accounts
- YouTube live streams with fake giveaways
- "Verify your wallet" to claim airdrop
Reality: No one gives away free crypto. You send, they keep it.
Red Flag: ANY request to send crypto first
6. Romance Scams (Pig Butchering)
What: Build fake relationship, convince victim to invest in crypto
How it works:
- Scammer contacts victim on dating app/social media
- Build relationship over weeks/months
- Introduce "investment opportunity"
- Show fake profits to build trust
- Convince victim to invest more
- Disappear with all funds
Average Loss: $10,000-$100,000+
Red Flag: Online romance + crypto investment = scam
7. Pump and Dump
What: Artificially inflate price, then sell for profit
How it works:
- Group buys large amount of low-cap token
- Coordinate "pump" - everyone buys at once
- Price skyrockets
- Organizers sell (dump) at peak
- Price crashes, late buyers lose money
Where: Telegram/Discord pump groups
Reality: Only organizers profit, everyone else loses
8. Fake ICOs/Token Sales
What: Fake Initial Coin Offering - take money, never deliver product
How it works:
- Create whitepaper with grand vision
- Build hype on social media
- Collect investments
- Never build product, disappear
Statistics: 80% of 2017 ICOs were scams
9. Impersonation Scams
What: Pretend to be support, influencer, or official account
Common Tactics:
- "Coinbase Support" DMs you about account issue
- Fake verified Twitter accounts
- Telegram admins asking for seed phrase
- Fake MetaMask support
Reality: Real support NEVER asks for seed phrase or passwords
10. Malicious Smart Contracts
What: Contract with hidden code that steals your tokens
How it works:
- You approve contract to spend your tokens
- Hidden code drains your entire wallet
- Or: Can buy token but can't sell (honeypot)
Prevention: Audit contracts, use token approval checkers, revoke approvals
11. Fake Wallet Apps
What: Malicious wallet apps in app stores
How it works:
- Fake wallet app looks legitimate
- You create wallet or import seed phrase
- App sends seed phrase to scammers
- Wallet drained immediately
Prevention: Only download from official websites, verify developer
12. Cloud Mining Scams
What: Pay for mining contracts that don't exist
How it works:
- Promise passive income from mining
- Show fake dashboard with "earnings"
- Can't withdraw or site disappears
Reality: 99% of cloud mining is scam
13. SIM Swap Attacks
What: Hijack your phone number to access accounts
How it works:
- Scammer calls your carrier pretending to be you
- Transfers your number to their SIM
- Receives your 2FA codes
- Accesses exchange accounts
Prevention: Use authenticator app, not SMS 2FA
14. Dusting Attacks
What: Send tiny amounts to track your wallet
How it works:
- Scammer sends tiny amount of crypto
- Tracks when you move it
- De-anonymizes your wallet
- Targets you for phishing
Prevention: Don't interact with unknown tokens

Types:
- Fake Marketplaces: Steal NFTs or crypto
