This is a major issue with most of the ventures these days, long term projects won't get good investment because the investors would want to make some fast money.
Sounds logical - so patience is affordable!
Indeed, investors want to earn money as quickly as possible, but let's not forget that a long and well-planned project will bring huge gains.
I do not think the investment will be less because of the duration of the project. It is true that the investment has a risk. but I think Ehealth deserves this risk.
It is one of the projects that all mankind needs. Medicine and the health branch is continuously growing. I don't think this project is a fail.
