I think a part of the problem for many of the ICO’s in early 2018 was that the value of the Ethereum raised during the ICO was worth much less in the aftermarket, which affected the efficiency of the projects.
At the same time the team behind RED has done a ridiculously poor job on the marketing side. However, this could very well change soon, as the product is ready for release soon. At the same time it has a market cap of just 1,3 mil, which means it is heavily undervalued compared to other projects in this space.
