Im choosing trusted manager in joining airdrops in which their works were already proven and seen that they are not scammers.Instances in finding airdrops risk is always at stake where we take alot of effort on doing our task and ended with being scammed.I think that we will never know  if we are being scammed if the Initial Coin Offering not been ended because there were also devs that scamned their bounty hunters inorder to get the full payments of the airdrops and leave us with nothing gained.It is better to have some sources on which airdrops that were about to join and what you did was a good start inorder that we can have assurance that our work would not be wasted and just leave it with a trash.
