Most ICO's tend to hide their members behind the project. Is not it necessary to know about the team also who are building an ICO project, including other factors of it?
Of course, it's very necessary to know the background of the team. Because today, projects that don't want to show their team, will intend to do a scam. That's why if the ICO project wants to succeed then they must be more transparent to investors. If they have many reasons not to reveal who their team is, be aware of fraud.
Some ICO web listings at this time also have a KYC system to verify ICO projects registered on their web to reduce fraud risks to investors and their loyal subscribers.
