As I learn, so far, scammers are very difficult to detect. They are always increasing their formula, their system, and their promotion to make all people interested and sure about the ICO. Scam ICo is not different with the legit one. However, if we can analyze more about their real team members, it may help us. Many scam ICOs can be detected from the profile of each team member. I also support to make strict regulation for any ICO to avoid scams. But, it will be also very difficult. Just this is our ways how to be smarter and more careful in picking the ICO.
