An airdrop, in the cryptocurrency business, is a marketing stunt that involves sending coins or tokens to wallet addresses in order to promote awareness of a new token or coin.
Small amounts of coins/tokens are sent to the wallets of active members of the blockchain community for free or in return for a small service, such as retweeting a post sent by the company issuing the currency.
A crypto airdrop is a marketing method employed by startups in the cryptocurrency space.
It involves delivering tokens to the wallets of current cryptocurrency traders, either for free or in exchange for a small promotional service.
The airdrop is meant to spread awareness and increase ownership of the currency startup.
While some are legitimate, other airdrops have been seen as fraudulent or scammy.
