This primarily depends on how much free time we have. If there is time, then in any case, participating in ICO bounty campaigns is better than wasting it. Although this year the number of new ICO projects has significantly decreased, at the same time, the level of fraud in them has significantly decreased and many projects, although they do not achieve great success in the price of their tokens, however, at the same time, they can hope for their growth in the future.
People need to be more careful what projects they support so they don't encourage scams. The problem is there too many "bounty hunters" that have no pride and just take on any projects and they don't really care and then they wonder why they making no profits. Yet the continue to do the same thing. I am beginning to think most "bounty hunters" are idiots.
Try not to take on so many projects at once. Carefully consider each one. Don't follow projects that look like every other project just with a different name and different story behind it. It is merely rehashes of what has been done 1000x before just with a new "look" basically just new templates or themes for the website and a slightly different pitch about something else but essentially is the same and what the project is about doesn't even matter since it is just fluff and nothing more. Yet people support this.
