Having a good team is one of the keys to success. Investors tend to research each team member and more ICO-experienced members are an added value.
Providing all neccessary information is very important for potential investors. Not showing all the information or lack of them can be perceived as an insecurity or uncertaintnty.
Potential investors want to understand the product and know about post-ICO plans and goals for the future. No plans equal no interest.
Reaching out to the potential investors and keeping an open communication with them is one of the most important keys of an ICO campaign.
