Bounty campaigns are not a waste of time guys, you just need to pick the right bounty campaigns to make some good money. Only participate in bounties where you think that the project has a good and strong team and also a good project that is really needed. I always prefer long term holdings if I participate in bounties!
Joining in and picking a good and legitimate bounty campaigns could have a high chance to become successful that would results to a huge potential earnings. And I think it could only be a wastage of time if a crypto user end up upon a scam.
