what they need now would be also an adviser pretty known in the whole world

who already made some hardcore deasease public or is a rockstar in the health sector.
For marketing and project launch it would be definitely a very good option!
i also think it would be a great advertising move to rely on a very famous public figure (actor, singer) who publicize the project, really need a lot of visibility for the success of the project...
That would be good when the platform will be launch to the market. But now I think that the good opinion of reputed doctors is more useful.
Right, there are some sports blockchain being advertized by famous soccer players, and that is logical - the people from the corresponding area inspire more confidence.
It does not matter whether they are advertising with a doctor or a celebrity, the important thing is that they attract attention in public.
