An airdrop is a distribution of a cryptocurrency token or coin, usually for free, to numerous wallet addresses. Airdrops are primarily implemented as a way of gaining attention and new followers, resulting in a larger user-base and a wider disbursement of coins. https://en.wikipedia.org/wiki/Airdrop_(cryptocurrency)
Usually we have projects launching, running events and airdropping (sending) their tokens to participants of these “Airdrop Events”.
We help by retweeting, joining and participating in the Discord (really just depends on whatever tasks you are asked to do for that particular airdrop) and then you get rewarded with tokens in return, sometimes these tokens don’t usually have much worth but along the way people buy in and the airdropped tokens rise in value.
Say for example there’s a new project on Solana and then they ask you to retweet and fill a google form with your address and twitter account, then the next day they send your airdrop and it’s worth 5 dollars but then there’s some hype about the drop so the value rises and your drop is now more.
