This project is very ambitious. It will be a revolutionary thing in the medical history if the concepts and products for this project have been reached.
Too bad we would have to wait for so long to see this project fully functional. 2025 looks pretty far to me. But for this kind of projects couple of years time frame would look suspicious. The team will have to do an enormous amount of work, I hope they have a good plan.
It also depends on with what motivation you invest of course. If you want to wait for the actual product in 2025, sure, but most people are also buying into an ICO to trade the tokens. That doesn't have to take long, an ICO token can easily 2x or even 10x a month or two after the ICO. Will be strong hands holding on till 2025 then
The problem is, a good push in price often happens when projects show something, even if it's just a small thing in the end. With an ICO which is scaled for such a long time, it could get quite difficult to get people to buy tokens more expensive on exchanges. But if they can show some progress with time, it should be easy.
