I know that FortFS broker which belongs to the same company that FortFC does offered cryptocurrency trading to the clients last year. They were satisfied by services quality. Thats why I doubt whether its reasonable to create a special project.
Personally, I think that it was made quick and dirty last year and that clients didnt get the quality of cryptocurrency trading that they needed. Thats why its needed to set up a special platform for this to make such services even better.
