⚠️ Common scams in the crypto world
1. Ponzi or pyramid schemes
They promise guaranteed high returns if you invest and recruit others. It is sustained by the money of new investors until it collapses.
• Example: Bitconnect, one of the largest scams in crypto history.
2. "Pump and Dump"
A group artificially inflates the price of a cheap crypto with rumors or manipulation, and then sells in bulk, leaving new buyers with losses.
3. Fake airdrops and contests
They promise free tokens but first ask for your private keys or that you send a "small amount" to validate your wallet.
⚠️ Never share your private key or seed phrase.
4. Fake wallets or fraudulent apps
Fake wallet apps or exchanges that steal your funds as soon as you transfer them. Some are even in official stores (like Google Play) before being detected.
5. Phishing
They send emails or messages pretending to be known exchanges (like Binance or Coinbase) to get you to enter your data on fake sites.
6. Celebrity scams
Fake advertisements or posts using the image of celebrities (Elon Musk, for example), promising to multiply cryptocurrencies if you send them something first.
7. "Rug pull" tokens
Projects that seem legitimate but, once they raise enough money, the developers disappear and the token becomes worthless.
• Very common in the DeFi (decentralized finance) ecosystem.
