I just find out that it's not easy to win going coinomi airdrops, I've participated in 10 different airdrops and never get paid at all so when I rechecked I always see like only 1000 people selected out of 300k or more, why airdrop in the first place when only few people will be selected ?
I have never been a fan of all these airdrops but I must admit that I have participated in a few and came out blank in all of them and like you said, there are too many people competing for few resources and the projects gets all the publicity from those huge number of participants. I have long forgotten about those.
