Unfortunately you and no one else can know whether the project or the scam will be 100% successful. Why? There are a lot of reasons, but there are basic reasons. Often the project can not raise money and as a result, a scam is obtained, but they can indicate the desired amount on the site that is already a fraud. As often greed for money takes up and when a good amount is collected, admins just run away with money and the project again scam. In connection with this, it's already hard to please what ico honest, and what will eventually turn out to be a scam. I propose to take the maximum number of projects for participation in order to reduce risks.
