While we must say that some are just to scam investors, we must also agree that some are not intentional, cus some developers really are honest but when they launch an ICO or IEO hoping to raise fund for the development of the project, and the money wasn't coming, instead of running away with the little they raised, they refund it back to the investors and close the project, in a situation like this, we the hunters shouldn't blame anyone cus already, we all should know that the going isn't going to always be smooth, at some point, things like this must happen and it's normal.
