Ehealth was the first to launch a long roadmap during short roadmap season of ico project. Now most are coming up with long roadmap upto 2020 ..
Short roadmap season
season of bull run and season of bear . Market trends and season ..
Most of the ICO's plan based on seasons only. In Bearish season most of them extend their ICO in order to get more investments. eHealth did well in planning but execution was a little sketchy.
