The time to complete an airdrop is very short. I don't think this is a waste of time because some airdrops still allow us to get a small amount of revenue. On the contrary, some bounty tasks that will take weeks or months to complete will eventually disappear. This is the most time-wasting thing!
well you have a point ,becuase it was also expirences even bounty campaign will be very good at the first time, but if the time will be distributed some manager will be gone or cut the comunication to any admin assign on this project ,,so that airdrop for my own opinon are also good if will also you have a payment but,if will not, both effort in time will be wasted.
