This thought just comes to my mind especially these days, with a lot of altcoins doing airdrops or giving away different altcoins.
But I got some confusion here when the "airdrop" term used.
Because for what I believe the meaning of "airdrop" is a way of giving a free coin/s to some wallet addresses without seeking any investment or doing nothing.
Are those spreading all over around especially in this forum known to be an "airdrop" is considered an airdrop or bounty campaign since some of those are requiring people to fill up some of the forms or need to sign up or follow some social media accounts, etc?
Since you did some task or work to get those coins.
The current airdrop is getting more and more confusing, even crazy things happened at coinmarketcap airdrop, for example 120k participants, but only 1000 winners, so 119k didn't get anything, airdrops are currently a cheap campaign tool.
