Common Crypto Scams Checklist: How to Identify and Avoid Them

There Are More Scammers in Crypto Than You Think

Global crypto scam losses from 2022-2025 exceeded $3 billion. This isn’t a small number. Where does this money come from? From beginners’ pockets.

Scammers target beginners specifically. Beginners don’t understand technology, don’t understand rules, don’t understand risk, and have a psychological urge to make money quickly — perfect victims.

This article lists the 6 most common crypto scams, with identification methods and avoidance strategies for each. After reading this, you may not become smarter, but you’ll become harder to scam.

Scam 1: Fake Coins / Vaporware Tokens

What are fake coins: Tokens with no actual utility, no technical backing, and no real team, packaged as “the next BTC” stories to attract beginners to buy. The project team dumps at high prices, the token goes to zero, and beginners lose everything.

Typical signs:

• Rough official website, vague information, anonymous or fabricated team
• No GitHub code repository, or empty repository (a few lines of code, months without updates)
• Marketing copy full of “disruptive,” “100x coin,” “next BTC” hype language
• Token distribution with over 50% held by the project team
• Community (chat groups, Telegram) filled with “go up go up” atmosphere, no one discussing tech or risk

How to avoid:

• Only buy coins ranked in the top 20 by market cap
• Don’t buy any small coins recommended in chat groups or Telegram
• Check coin info on CoinGecko/CoinMarketCap, don’t blindly buy on any exchange’s “new listing” page
• Check the project’s GitHub — don’t touch coins without active code commits

Scam 2: Phishing Websites

What is phishing: Websites that mimic legitimate exchanges or projects, making you enter account passwords or private keys on fake sites. Scammers steal your information and then drain your assets.

Typical signs:

• URLs extremely similar to legitimate sites but with one or two different letters (e.g., gate.lo instead of gate.io)
• Links sent via email, SMS, social media DMs
• Website interface almost identical to the legitimate site
• Asking you to enter your private key or seed phrase — legitimate sites will never ask for this

How to avoid:

• Only access exchanges through official channels (bookmark the correct URL, don’t enter via links)
• Don’t click any links in emails/SMS/DMs
• Check if the URL is correct — examine every letter carefully
• Never enter your private key or seed phrase on any website

Scam 3: Pyramid Scheme Coins / Ponzi Schemes

What are pyramid coins: Tokens promoted through referral networks, where early participants’ profits come from later participants’ investments — a classic Ponzi structure. No real business backing, inevitable collapse.

Typical signs:

• Requires you to “invite friends to join” for rewards
• Excessive return promises (5%+ daily, 100%+ monthly)
• Multi-level commission structure (your referrals refer others, you earn多层 commissions)
• No real product or service, only “hold coins and earn returns”
• Project promises “guaranteed principal and returns” — no one in crypto can guarantee this

How to avoid:

• Don’t participate in any project requiring “recruiting people”
• Don’t believe any “guaranteed returns” promises
• Projects promising over 20% annual returns are likely problematic
• If the project’s revenue source is “new user investments” rather than “real business revenue,” it’s a Ponzi scheme

Scam 4: Exchange Exit Scams

What is an exit scam: Small or unregulated exchanges that attract users to deposit assets, then suddenly shut down, with all user assets lost.

Typical signs:

• Short operating history (under 2 years)
• No transparent team info or company registration info
• No public cold wallet addresses or audit reports
• Abnormally low fees or excessive registration bonuses (too low or too high compared to mainstream exchanges)
• Community reports of withdrawal difficulties or delays

How to avoid:

• Only trade on mainstream exchanges (Gate.io, Binance, OKX, Kraken, etc.)
• Don’t deposit large assets on small, new, or unknown exchanges
• Transfer large assets from exchanges to your own cold wallet — exchanges are trading tools, not savings accounts
• Monitor exchanges’ public audit reports and Proof of Reserves

Scam 5: Social Media Scams

What are social media scams: Accounts impersonating celebrities, project teams, or official exchange accounts, sending false information to诱导 you to transfer funds or click phishing links.

Typical signs:

• Account names extremely similar to celebrities/official accounts, but not the real official account
• Sending “limited-time giveaway,” “free airdrop,” “urgent notice” messages
• Asking you to send coins to a specific address “to participate”
• Replying in comments “DM me to help you” — then the DM is a scam

How to avoid:

• Only follow verified official accounts (blue verification badge)
• Don’t send coins to any陌生 address
• Don’t believe any “free giveaway” or “airdrop” messages
• Verify official accounts: find social media links from official websites, not websites from social media

Scam 6: Fake Customer Service / Fake Tech Support

What is fake customer service: Impersonating exchange customer service or project tech support, proactively contacting you to “help solve problems,” but actually trying to获取 your account information or make you transfer funds.

Typical signs:

• Proactively contacts you (legitimate customer service never reaches out first)
• Asks for your password, 2FA code, or private key
• Asks you to transfer funds to an address to “verify identity” or “unfreeze account”
• Presses you to act quickly “otherwise your account will be frozen”

How to avoid:

• Only contact customer service through official exchange channels (website live chat, official email)
• Don’t respond to any “customer service” that proactively contacts you
• Legitimate customer service will never ask for your password, 2FA code, or private key
• Legitimate customer service will never ask you to transfer funds

Summary

Six common crypto scams: fake coins/vaporware, phishing sites, pyramid schemes/Ponzi, exchange exit scams, social media scams, and fake customer service. Core identification principles: excessive return promises = scam, proactive contact = scam, asking for private key/transfers = always scam, wrong URL = phishing.

Defense strategy: only buy top 20 market cap coins, only use mainstream exchanges, only access and contact through official channels, don’t transfer to strangers, don’t enter private keys on any website.

Demon Law’s First Rule: Acknowledging weakness is the first step. Admit you’re a beginner, admit scammers are smarter than you, admit you can be easily scammed — then you’ll stay vigilant, rather than thinking “I won’t be scammed.” Confidence is a scammer’s best ally; vigilance is your best defense.
