The best airdrops in the world of cryptocurrencies come from strong projects with a known development team and a clear plan. Some of the most famous examples of airdrops are Uniswap and Arbitrum, which distributed free tokens to their early users and made huge amounts of money. To benefit, follow trusted platforms like CoinMarketCap and Airdrop Alert, and register for new projects that offer real services. But be careful of fraudulent projects; don't share your personal information or wallet with anyone. Airdrops are a great opportunity to earn without paying, but you need to be smart and choose wisely to benefit without exposing yourself to harm.
