Reviewing airdrop scam cases can help investors avoid fake projects. Common scam tactics include promising extremely high rewards that seem too good to be true, using fake social media accounts to promote the airdrop, and asking for personal information or payment in exchange for the airdrop. To avoid falling victim, always verify the authenticity of the project. Check if the project has an official website, a whitepaper, and a verified team. Look for reviews and discussions about the project on reliable cryptocurrency forums. Be cautious of projects that use high - pressure tactics to get you to participate and never share your private keys or sensitive information.
