That is, this company will attract investors for this project through its own channels?
Yes and Opthereum cooperate with other companies. At the site of Optherium and in social networks and here on Bitcoin you can find all information about the development of Optherium.
I confirm this fact because I myself saw on the project site a list of team partners. The team does not hide its partners. All important information is published on the project website and in social networks.
