I deeply understand that market need protection and that investors needing it too, but... what about Creator/Project Founder? If Creators have starting capital, maybe they can fund investor by himself, not needing a expensive Crowdfunding campaign.
Mentors and Incubators already ask to the Creator a lot of money to "certificate" business model and business plan, marketing strategy and team skill.
In other hands, Investors have a good opportunity to get great revenues from a success project and... in my mind, where a great revenue is possible then a big risk is included. Don't you?
