Investors may gain their trust in a certain project if the team shows details or information about their experiences and expertise in work.
It will surely be a big thing to consider since we all wanted to know who is behind the project. This is a serious matter which it is really necessary to have this kind of information so that people will be having no doubt about the project.
I disagree with you, in ICO stage, team ask for money to build their platform, therefore it's important for any investor to know who behind the project before giving his money. Later when you build a the platform, people that come to your platform are customer that will use your product and not investors.
Care to explain how this project " already have its advantage to the other crypto project here" since I don't see much details on that one thing
