Hi bro, I have a same problem, like you. In my opinion, I usually choose that bounty, what is running by good bounty manager.
yes maybe what you say is true too, usually most will look for bounty campaign projects from well-known managers, such as amazik, artezy, hotachy, etc., but that has not yet determined the success of each project. I am the same as you are a beginner, but I always do every research from every project that I will follow. even though like that sometimes there is only at the end that always ends scam
