Wow, you have a really generous Bounty pool! Can you elaborate on the abstract program, I do not quite understand how this works? And If the project does not collect the necessary amount of investment, will the participants be rewarded?
Yes, of course, the conditions are pretty simple! Inviting a friend you both get 5% of his purchase. Also there is a referral Bounty program, by inviting a friend you both get 5% of his reward. I can not say for sure whether the participants will be rewarded, you should contact the organizers or the manager with this question.
