What are the most common types of cryptocurrency scams?

Common cryptocurrency scams include: Phishing attacks where fraudsters create fake websites to steal login credentials; Ponzi schemes promising unrealistic returns like BitConnect; Rug pulls where developers abandon projects after collecting funds; Impersonation scams via social media pretending to be celebrities or exchanges; Fake exchanges stealing deposits; Romance scams luring victims into investing; Pump-and-dump schemes manipulating altcoin prices; and Giveaway scams requesting upfront payments. Always verify official websites, enable two-factor authentication, research projects thoroughly, and be skeptical of guaranteed high returns. Never share private keys or seed phrases.
