Is there any topic with the terms we use here on forum?
Airdrop is a form of promotion where members of a project promotes the said project and are rewarded with the platform's token, thus it is a free token given for performing various activities. During airdrop campaign, the team who launched the airdrop will set and arrange the activities to be carried out; it could be to invite members to the group, follow on Twitter, tweet a post, retweet and like a post, follow on Facebook, share and like a post etc. The activities are created by the team so it can vary depending on what they want to achieve. Also, through airdrop the activities within the platform increases thus leading to more engagement and so on. Lastly, Airdrops are given for free so far a member did the right thing, therefore airdrop asking for payment before being rewarded is scam, any airdrop asking for private keys etc is also scam..
