One thing I understood from people that have success in trading is that they follow the people behind the currency they invest in, and the news. This give them an overview of the potential pump of their coins.
Another thing is checking the community behind the coins.
And finally a lot of youtuber, Facebook groups/pages provide some interesting information and point of views. And sometimes they even share information from dedicated websites that you can then follow!
Basically this is what I do to get information for the trades I do.
