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 ?
If a project starts to show signs of fraud, they will abandon investors and questions on their telegram channel. they will not distribution on time or to dealine to distribution the bounty without a notice for the return date. there is even a project that offers thousands of reasons to cut down on the amount of bounty hunter payouts. I had a project after the end of the bounty, the amount I received was only one-twentieth the amount I deserved.
