Sometimes its always better to listen to your heart, after learning how to do better research on projects i end up listening to few friends because they are the ones that introduce me to bounty hunting not knowing that i have surpass them, every bounties they told me to promote are bad but the ones i choosed myself are
1. Zeux
2. Collectrix
3. Ferrum network
...
I also plan joining in those campaigns before but been busy in personal life as the bounties isn't paying those times too. Just learn from this experience of yours now OP. Next time follow your research and instincts since some might only using you since they also joined in that bounty or will have a reward for referral. As long as you know you research the project and feels it will be successful then go do it.
