#ArizonaBTCReserve An **airdrop** is a free distribution of cryptocurrencies or tokens, often used by blockchain projects to promote their platform or reward the community. Users can receive tokens simply by holding a certain cryptocurrency, registering for a project, or completing simple tasks (such as following social media channels). Airdrops serve to generate interest, increase adoption, and decentralize token ownership. Some airdrops, such as those from Uniswap or Arbitrum, have brought significant gains to users. However, it is important to be cautious of scams: never share private keys or sensitive data to participate in an airdrop.
