so if you check, you did see that these airdrops do give people money. What you've to consider is;
1. The Chain they're been developed on,
2. What Impact can it give and are cex putting interest in it?
3. most importantly patience. Patience is the Ultimate you need to have in this Crypto Ecosystem in general
The third point above I think does not only apply to airdrop participants, like me, you and all of us here who have or have not invested are also more or less required in this regard and for points 1 and 2 above also seem to be major items that must be explored before participating in their campaigns.
Whatever the campaign, if there is found a hidden spot, not many people who follow the campaign will be very extraordinary to be generated because the competition is small. If it is hype once, the opportunity to get more will be small.
