I considered the possibility they want to promote the concept of STOs, because without projects to host there is no point having an STO platform. But does that make sense if technically the DUSK project is still in research phase? What if at some point during research it turns out the concept is not viable?
I am sure they did some preliminary research before they went in to this project otherwise they threw away a lot of money but how this will work in real life and how will this work with other devs is still a question which needs time.
Hosting STOs would surely be good for the valuation of the platform but there are many legal uncertainties which make me believe that STOs will not be a big thing before 2020. Until then a lot can change in either direction.
