$USDC To avoid airdrop fraud, be wary of red flags such as unsolicited messages, requests for private keys, pressure tactics, suspicious URLs, promises of guaranteed returns, and requests to send cryptocurrency upfront. Prevent fraud by verifying official sources, using trusted wallets, enabling two-factor authentication, being cautious with links, never sharing private keys, and doing research before participating. Practice security by keeping wallets updated, double-checking airdrop details, using cold wallets for large storage, and reporting suspicious activities to protect yourself and others.
