what is airdrop and how do i get them?
Airdrop is a free token given by a new project maybe for them to make their coins popular and for them to make their token or coins to increase its price. They are not just giving free tokens but also they have bounties.
Good explanation mate! Very easy to think like this; just imagine coins are dropping from air almost like rain drops and you get them. Most of the time only thing you need to do is just sign up for that airdrop to receive your free coins / tokens.
