For me the best one to follow with some good output is the icodrops. They arent just posting new projects but also informing users if you are following their telegram announcement section, about some great news about different projects. I usually seen new ones being offerend and even release sales and date. Very good platform for scouting and acquiring new projects.
Icodrops have been running for some time now but they are only for getting a list of upcoming projects.
The main thing that should come from the investor's side is the research done on the project, its advisors and their background, profit making methods and potential competitors. Because often it has been seen that advisors leave all of a sudden selling their stake and moving to another project - it is their nature to move like that. Yet again the project might just have some face value and not method to generate an intrinsic market demand, in which case it is a bust in the long run.
All these factors come into view when doing research and often scams get identified because of this. Tracking what a site publishes is fine but that should not be the determining factor to buy a coin.
