If you're thinking about trading then that's a whole different area of study and mainly about psychology, both yours and the market's. By all means read up about crypto too but the really important stuff regarding trading has little to do with its specific ins and outs.
I think the input and output of capital flow in crypto market are important and it help us to know about the momentum of the market. The strong momentum, the bigger chance to see a trend keeps going up and vice versa. When the price is at low range and momentum suddenly see signal of increases I think it is a good signal for bull run.
When price is at high and momentum see sudden falls it is not a good signal and it it last for a while the bear market comes.
