Hi guys , recently I was interested in tokens with airdrops but what are they finally ? Could someone help me please ?

Token is rewarded to someone who fulfill their duties like accepted to join of Signature campaign of any bounty campaign token meaning is made by any different Flatform they build after they gave you token there is an equivalent value in ETH or dollar. you just try to join in any different campaign to experience what's the feeling if you received a token reward.
