I'm still wondering why developers will organize airdrops and distribute an amount of tokens which is far lesser than the minimum amount of the tokens that can be deposited on an exchange for trading. If you don't want the users to cash out the money, why do you let them waste their time?
I think the purpose of airdrop is to fill their social media with crowd of peoples.
The more peoples join and supporting the project, the more investors will be attracted to investing.
Airdrop participants can hold their token for better value in the future if they cannot deposit it due low value.
Airdrop is not even supposed to be in large quantity, its just a small token distributed free to create further awareness, if they spend all the project money on campaign, how do we then expect the project to survive, so I wonder why people complain on things like this.
Airdrop is free and some doesnt really demand much from one to have access to, and since its free and little, the receiver can further invest in it if he or she finds the project interesting, or like you said.
Just continue holding till the coin gain a special value in future, by the time he counts the number of airdrop he has, and he would be amazed at what they are capable of gaining in future.
