Even if you think that they are scammers which is your choice, why would not put then coin on exchange as that would bring more money so your FUD is no logical
There are dozens of projects, and I can tell you that if they are scammers, they will definitely put the token in exchanges, so they will earn even more, second, this project has already proven to be genuine, is very difficult to scam people nowadays, just check the forum, and you will see all the legitimate projects, search youtube, web pages that can verify the authenticity of a project, etc., it's up to you being cautious though.
