may have existing products or proves to be indeed made quite confident in investing. but just a real product alone is not enough in the absence of the concept and the elaboration of the product system. so from those other advocates such as whitepaper still need to be used as supporting materials. ICO will be able to provide a nice clear description including the whitepaper as this will help clarify the concept of the ICO.
You know one thing about having an existing product and have been able to create some sort of little demand for this product to actually have a feel in real life how things would be like for the usage of the products by users, always tend to go a long way when it comes to investing in such product. I always see funding as a way of building on what is already available and helping the product to grow more than it already is, when it comes to marketing and some other sort. I wonder why people tend to focus on a whitepaper that can be cloned or some empty promises. Team, minimum viable product, and the vision, speaks well than just a whitepaper.
