Yeah. As i said in the subject, is it really worth it?
I mean is it really worth learning how to read its chart?
Having no clue at all is the worst thing you could do. Decisions made with just an assumption without any form of analysis will lead you to the unfortunate cases. You have to be at least aware of chart prior to dealing up with a certain decisions, so yes, it matters it may sound so tiring, and complicated but it plays a vital role to avoid further loss.
