I'm sure that you guys have experience doing bounty for months and when you are very lucky that you got paid then you check the value of your tokens, it's only $10-$20 in total. It is so heartbreaking to witness that kind of moment. And now I realized that maybe I'll try investing in IEOs and stop bounty hunting because it's the only thing that can make me profit again.
I do agree with your concern and even i have problem same like you, investing in IEO's is always a good way to make money if you manage to hold them for a certain period of time. In the same way, you can research more about the bounty campaign because most of the potential coins are showing their credibility even after listing in the exchanges.
