don't waste your time on projects like that and you better choose projects listed on other exchanges, for example from bounty detective I see a lot of their projects listed on the exchange are more promising than azbi it's just that I don't know whether the reward is guaranteed or not .
That's the right thing to do, look for a better options and opportunities like what you said. Bounty Detectives has a plenty of goods projects but the thing is that being with a good projects meaning a lot of participants would join and less rewards for every participants plus, most of the projects that BD is handling have low pool rewards that makes even lower bounty rewards for bounty hunters.
