Yes the road Is still long for the project I think, let the ico finish before think about listing. I think the project ha an interesting potential, If the team handle it in long term like they planned, the futur of the project could be really good.
The best time to be listed on exchange will be after the token sale end. That is the fair and good thing to do for a project. Ehealth is a long term project and talking about listing is a bit too early.
