I'm always doubtful with regards to participate in many airdrops since I know it is just a free tokens which we are not sure if they really give the tokens or just collect the details of every participants purposely for the record.
The risk of participating with bounties, as if you are not careful those signed up will possibly harmed you without recieving anything in returned.
For me, I will give a shot once there is so potential airdrop with transparency and back up by the professional team.
So do I, it's much better to check first the team behind and how useful the project might be.
The project with strong team can achieve great success after the promotion using airdrops.
And if does, those tokens will soon gain value, it will bring good profits to you.
