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 they are simply just using that as marketing strategy to create more awareness for the project, but I see it as a very wrong method of marketing because those that are getting the airdrop may not even pick interest in investing in their project, because virtually those who request to participate in airdrop are simply doing so to get free coin.
If I were those project developers and I am sure that the project has a real working product, I will rather prefer to use that airdrop fund to market that product through other social media platform or bill boards and from there introduce the coin to them, because airdrop is just a waste of money to me.
