If you have frequently reviewed the activities on each project it will be easy to identify scams from new projects, their project scheme will always be the same and only replace the new project name and slogan to attract novice investors, so always check the project so it will be easy to recognize good projects and scam projects, both will surely differ even though scammers have the skills to make web appearance, whitetaper and etc look real but no scam is perfect.
Exactly, we can easily find out the characteristics of scam projects and for simple research then you can review bounty projects, if we can conclude potential projects and scam projects with simple research, the simplest feature is that they don't provide telegram or discord conversation services to avoid questions from members and investors, avoid scam projects by conducting detailed reviews for project/bounty analysis.
How is bounty campaigns helps to conclude that a project is a scam? Having a bounty project doesn't mean the project is indeed a scam or a legit project. I believe that there little to zero project that don't have a communication platform that they are using at the least. It's an untold mandatory thing to connect with your community by having a channel that you can talk to, Even scammers create one themselves because it is how they persuade their community on investing into them. There are various kind of research to do in a project and I believe that relying to the existence of their telegram or discord won't do a thing.
