for those who dont have any idea of what crowdfunding is let me enlighten you.
crowdfunding is a combination of microfinancing and crowdsourcing. The result, individuals come together to help support projects and companies across the world. These people front the money in the start-up of a small business, either as a gift or with an expected reward or return.
Ya. Individuals come together to support the project for common goal. If theyve invested in the project, it is a much that they also need to support the promotion of their ICO so, when the ICO succeeds all of them benefit from the project as well as the implementatios.
