Airdrop
An airdrop is a distribution of a cryptocurrency token or coin, usually for free, to numerous wallet addresses for marketing purposes.
An airdrop is a type of airlift in which items including weapons, equipment, humanitarian aid or leaftlets are delivered by military or civilian aircraft without their landing. Developed during World War II to resupply otherwise inaccessible troops, themselves often airborne forces, airdrops can also refer to the airborne assault itself.
