Currently i am participating in bounty program and signature campaign so consider airdrops as cheating trap. But i am working on some new telegram mining bot. I have participated as a newbie and have been mining several projects. You may get some best airdrops but not good profit from it because there will be many airdrops hunter participating.
The more airdrop hunters who join a project, the less allocation will be obtained for each participant.
If there are no restrictions on airdrop participants, all allocations will be divided equally by the number of participants.
But some airdrops also limit members who join, so the rewards they get are still quite worth it.
I have joined dozens of airdrops and some airdrops provide big rewards and many also give small rewards and also do not pay aka scams.
