🚩 Red Flags: Universal Warning Signs

🚨 TOO GOOD TO BE TRUE

  • ✋ "Guaranteed returns of 10%+ monthly"
  • ✋ "Double your money in 24 hours"
  • ✋ "Risk-free investment"
  • ✋ "Get rich quick with this coin"

Reality: Even best hedge funds average 15% annually

👤 ANONYMOUS TEAM

  • ✋ Team members use fake names/photos
  • ✋ No LinkedIn profiles (or fake ones)
  • ✋ "Team hidden for security"
  • ✋ Founder photos stolen from internet

Check: Reverse image search founder photos on Google Images

📱 PRESSURE TO ACT FAST

  • ✋ "Limited time offer - act now!"
  • ✋ "Only 100 spots left"
  • ✋ "Price going up tomorrow"
  • ✋ FOMO (fear of missing out) marketing

Rule: If it's real, it won't disappear in 24 hours

💬 CELEBRITY ENDORSEMENTS

  • ✋ "Elon Musk endorses this coin"
  • ✋ Pictures of celebrities with logo
  • ✋ Fake tweets from famous people
  • ✋ "As seen on CNN/BBC"

Check: Go directly to celebrity's Twitter - they almost never endorse coins

💣 Common Crypto Scams Explained

🪡 Rug Pull Scam

What it is: Developers create coin, promote it, collect investor money, then disappear with all funds.

📊 How it Works:

  1. Launch new coin ("XYZ token")
  2. Heavy marketing: Twitter, TikTok, Discord hype
  3. Price pumps (early investors cash out)
  4. Developers "remove liquidity"
  5. Token becomes worthless, devs vanish

💰 Real Example:

SafeMoon (2021): $1B raised. Developers repeatedly called for more investment while secretly selling. Investors lost billions.

🛡️ How to Avoid:

  • Check blockchain for liquidity locks
  • Verify team on LinkedIn
  • Read code on GitHub (genuine projects publish)
  • Never invest in coins <1 month old

🎣 Phishing Attacks

What it is: Fake websites/emails trick you into revealing seed phrases or passwords.

📧 How it Happens:

  1. You receive email: "Confirm your MetaMask wallet"
  2. Links to fake website (looks identical to real one)
  3. You enter seed phrase or password
  4. Attacker drains wallet

⚡ Common Variations:

  • Fake Coinbase/Kraken login pages
  • Discord DMs impersonating mods
  • "Verify account" links in Telegram
  • Malicious Chrome extensions

🛡️ How to Avoid:

  • NEVER click links - type URLs directly
  • Verify URL starts with https:// (green lock)
  • Use hardware wallet (protects even if computer is hacked)
  • Official teams NEVER ask for seed phrases

📈 Pump and Dump

What it is: Coordinated group artificially inflates price, then sells off, leaving latecomers with losses.

📊 How it Works:

  1. Insiders buy large amount quietly
  2. Hype on social media: "This coin will 10x!"
  3. Retail investors FOMO buy at peak
  4. Insiders sell their entire position
  5. Price crashes, retail loses 80%+

💰 Real Example:

Dogecoin (2021): Pumped 10,000% in weeks due to celebrity hype and social media coordination. Many latecomers lost significant money.

🛡️ How to Avoid:

  • Suspicious of coins pumping 100%+ in days
  • Avoid coins with heavy social media hype
  • Check chart volume - authentic movement = steady volume
  • Never buy at all-time highs

🔁 Ponzi/MLM Schemes

What it is: Early investors paid with new investor money. Collapse when new money dries up.

💸 How it Works:

  1. "Stake 1 BTC, earn 10% monthly"
  2. Platform pays early investors from new deposits
  3. Looks profitable so more people invest
  4. Eventually new sign-ups dry up
  5. Platform collapses, last investors lose everything

💰 Real Example:

OneCoin: Promised 200x returns. Generated "returns" from new investor deposits. $4 billion stolen. Founder sentenced to 20 years.

🛡️ How to Avoid:

  • No platform guarantees returns
  • Question sources of returns (what generates revenue?)
  • Avoid MLM structures ("recruit others for bonuses")
  • If it sounds too good, it is

✅ Your Crypto Safety Checklist

Only invest in top 20 cryptocurrencies (BTC, ETH)

Or coins with 5+ year history

Use hardware wallet for large holdings

Ledger or Trezor ($100-200)

Enable 2FA on all exchange accounts

Authenticator app (not SMS)

Never share seed phrase with anyone

Not even with customer support

Verify all URLs before entering passwords

Type manually, don't click links

Research team before investing

LinkedIn verification, GitHub code

Only invest what you can afford to lose

Assume total loss = don't invest

🎓 Remember: You Are the Target

Scammers target crypto investors because:

  • 💰 Money: $14.4 billion lost yearly = worth their effort
  • 🌍 Global: Blockchain is borderless, hard to prosecute
  • 😎 Psychology: FOMO (fear of missing out) makes people careless
  • 🧠 Knowledge Gap: Crypto still new - many don't understand how it works
  • 🔓 Your Only Defense: Education and skepticism

❓ Preguntas Frecuentes

¿Perdí cripto en una estafa, qué hago?▼
Lamentablemente: No hay vuelta atrás en blockchain. Las transacciones son irreversibles. Lo importante: reporta a policía (levanta denuncia), y usa para aprender. Mejor prevenir que lamentar.
¿Cómo detectar un sitio falso?▼
Señales de phishing: Dominio ligeramente diferente (coinbas3.com vs coinbase.com), solicita contraseña, presiona urgencia. Siempre: Escribe URL directamente, NO hagas clic en links.
¿Las celebridades realmente promocionan cripto?▼
Algunos sí, pero la mayoría de fotos son FALSAS. Verifica yendo directo a su Twitter oficial. Si ves "Elon respalda XYZ coin" en email o ads: 99% ESTAFA. Las celebridades no avalan coins oscuros.
¿Qué hacer si me hackean la wallet?▼
Inmediatamente: Si es hardware wallet (Ledger): imposible, tranquilo. Si es software (MetaMask): cambia seed phrase en nueva wallet, recuperate de backup. Usa hardware wallet para el futuro.
