It looks very incomprehensible and difficult. I wonder how much time is needed to learn how to understand the graphs of coins and make predictions...
I say it is not hard to understand if something is rare and a lot of people want it you expect a high price. Something maybe a lot better and functionally and a lot want it, but if lots available price cant move.
For example some of the street artist painting with spray cans or brushes or what ever are really special and great looking so you buy one as you have use for it in your place. Tomorrow you walk the same way and look again at the beautiful artwork you got the feeling todays look even better with more vibrant colors, will you buy again? You continue on the way and there is another artist slightly different style if better or not is arguable. Further on there is another one producing top quality work and so on......
The price want reach astronomical levers because just to many are available.
When something is very limited or just a single piece, price can go through the roof, like recently with this painting.

A Hotel or Plane which is nearly sold out prices rise dramatically.
