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?
It's a bad marketing strategy in my opinion.
Let's say if they sent 1m token to 50k addresses then maybe almost 50k peoples will know about the project and those 50k peoples will probably look for the price and will also try to learn more about that project.
Maybe some peoples will convert and will do promotional works (bounty) for them to earn more of those tokens. And from promotion, they may get investors to get funded up their project.
They send such low amount because they don't want peoples to dump the tokens when they will list the token in exchange. It's just a marketing startegy imo, and win win thing for them.
It's a good marketing strategy. I once joined an airdrop and it only took 10 days for my airdrop worth reaches 1000 usd JUST FOR FREE. And they only gave some coins to lucky 1000 people and I only waited for 10 days just to have 1000 dollars. Just imagine. Hodlers of a coin makes the coin's price go up.
