At a point the team start given excuses to abide by what they promised to do or stop communicating with the community then I can sense the project is scam. How do you determine a project is gone bad and won't fulfil it promise? What criteria do you use ? or you wait for years thinking all will be well ?
There are many criteria for analyzing and comparing projects, when you begin to seriously study all the nuances, then basically you immediately see what the platform is and what its success is in the future. It is equally important, what goals the creators pursue and how much they are involved, in the development of their ideas. Because some projects simply copy others for enrichment and usually this is immediately apparent. When you begin to read documents, for example, to write an article, you begin to understand where all this will lead. Sometimes you just wonder and think that's it?
