Based on my experienced before. Yes it is hard to recognize if the project is scam or what. Because if you'll see the team behind of the certain project it looks like real, but when the game runs, everything turns to nothing and your time and efforts just for nothing. It is really hard to recognize if the project is real or not, I hope someday that they will make a security before a team create a project. They will get some important or supporting identification of the team, so that we can try to reach them if there's something wrong in the project.
