Most of the airdrops are like that. You have to engage with the project's platform and participate with the quests and challenges that they're giving to everyone. That's why the rewards are distributed based on how active a participant is on their platform and not only that, there are many ways for them to give better points to the participants. And one of them is about buying those points and selling them to the investors. This is what the others are choosing but they are ready for their deep pockets to comply on it and those that have no money should stick to the quests and challenges.
