I feel sorry for everyone that participated in this bounty and wasted a lot of time and energy to get 0 reward in the end. I mean it's a different thing, if you participate in an altcoin bounty and then the bounty reward is basically worthless because the project never really was successful or if you get completely scammed like in your case. I also have to say though that stuff like that is happening quite often, especially in altcoin bounties. Sometimes it's a bounty manager that is a scammer and sometimes the project dies so fast that it won't survive till the final day of the bounty. You always need some luck and intuition to find good altcoin bounties.
