An airdrop is when a company or project gives away tokens or coins to a large number of people for free. This is usually done as a way to promote a new cryptocurrency or token, reward existing users, or encourage people to participate in certain activities.
To be eligible for an airdrop, you might need to hold a specific cryptocurrency, be a member of a particular community, or take part in social media campaigns. Sometimes, the ecipiernts of the airdrop are chosen randomly or through a lottery system.
The idea behind an airdrop is to create buzz about a new cryptocurrency, reward loyal users, and attract new people to the project. They’re often used as a marketing strategy to help a new cryptocurrency get off the ground and build a strong user base.
