Airdrops are no good. The largest amount I got from one of those has been 25 bucks, a laughable sum for even spending the time looking for it.
Yes, airdrops have such a low value that it's a waste of time to deal with it. The time spent searching for some sensible airdrops is not even proportional to the profits that can be gained.
Me too, participating in airdrop is just wasting our effort and time because the amount we earn is too small due to so many participants who divided the airdrop rewards allocation.
