So if someone will not do that, I do not see them buying tokens because I have air dropped them free tokens.
You see, airdrop participants can get up to $5 in tokens, so it can't be a reason why they won't buy more tokens. Usually, airdrops are used to attract community. Something like free candies. )
Well, many projects use airdrops. It is always better when the community consists of 40k participants, but not 1k, right?
