I think products is very very important for a project. Investor see that the project road map and working step by the road map. If there have products or app or more physical thinks they can believe this projects. It's just my opinion
because of the current state of the crypto-currency market for investors, each project has become risky. Of course, if there is a finished product, then the risk decreases and then there are all chances for the investor to get a real profit.
