> There is one project with a 3-month ICO program but it's barely getting investors. This is the reason why most ICOs only last for few days or max 20-30 days to get investors quickly so that they can start implementing their project.

I get the feeling most of these ICOs are designed to be so short just to maximize FOMO (Fear of Missing Out)

I am just learning about ICOs now;  have any used, for example a Dutch Auction process for greater fairness?
