According to the road map, I did not see the open testing phase. I think that in 2019 the basic version will be offered already for working with the platform. But I also would like to see the interface before.
Testing will be performed for the application partners. We will be able to evaluate only the quality of the finished project. But the situation may change. I think the developers will report it during the ICO sales.
At the moment, as investors, we will not lose anything. We will need to wait for the response of the team about their intentions to conduct ICO and implement the project as a whole. I think it's going to be all right.
