We usually think about free is totally free like just an airdrop. But actually, all of those things are not totally free. It is only a reward for completing a simple task. I don't think it is really encouraging but for those who did nothing, why not try?
I could say that this is a good way to start earning in crypto for newcomers but just to remind them also that be sure that they are visiting the right/legit site otherwise, they are just wasting their time. And aside from that, we must not expect huge rewards.
to expect big rewards we can collect prizes then we can invest in potential coins, I have been doing this for a long time. but I'm looking not from airdrops, but from signature campaigns. It would be a shame if we didn't try it, even though currently the prizes are not as big as in 2017, there's no harm in trying to get a little prize, which of course can be useful, as well as expanding knowledge about cryptocurrency. Even though sometimes I don't get a prize, I still faithfully participate to try my luck
