I can say that for me bounty campaigns are not a waste of time. I do a lot of research and always try to figure out if the ICO is legit before participating in bounties. That saves a lot of nerves.
Actually working on bounty campaign are not wasting of time, Ill think to those person are not willing to doing bounty can say bounty campaign was a waste of time. Ill earn a lot in bounty campaign so why we say the bounty a waste of time.
