U can use telegram channels
They gives signals about coins
Yeah, it would be a great help to view a telegram channel but I will advise to not buy any coin just on the current results. What I am trying to say is the past performance must be checked out first and then future predictions by some experts must be consulted.
This will clear many doubts of any person. In my opinion, bitcoin is the only coin that should be at the top of making investment. Experts are of the view that it will cross 10k dollars within first half of 2018.
