This makes me remember an interesting topic I read in the past which describe perfectly why 99% of ico are 'absolute garbage' because they are giving a good percentage of their total allocation to random people doing specific advertising tasks like Facebook and twitter campaign with most of them full of bots accounts thus they are not generating any revenue and the bigger problem is that even legit bounty doesn't apply any form of tracking to evaluate the effectiveness of each participant. Also, not having maximum numbers of participants lead to a hard dump on tokens price after launch as know hunters tend to sell their reward immediately when received.
