Research. Ask questions. Use all the research tools and take advantage of our high technology world. We cannot learn if we don't know how to do research. We will not know things if we are lazy. Sometimes it pays to make use of research tools to know something.
A lot of reliable information now are available online, it depends how resourceful we are and how much time we spend doing the research. I guess it can also help to join some groups of crypto users because based on my experience, once a member found any helpful and informative news they will share it with the group.
