Yes this is what we keep looking because that will validate what future this project is and of course their roadmap and whitepaper , though in time this has not been the basis yet if there is a good team behind then their paper and maps must be accurate to serve their investors and bring them assurance to what they might be looking forward.
and also for them not to fall from being seller when the coin/token enters the exchange in which many investors are doing even from the past.
The roadmap will give us the additional information about the project,in most of the announcements thread the trader can use the roadmap section to know more about the project in detail.Because the roadmap had the original owner detail and the every quarter plan of the particular year.Even you can check the owner profile in the social media to know the real project or not.Investing at the right time was the good way of trading to get good win from the trading of the project.The listed exchange also play the huge role in the liquidity of that particular project.
