What pattern are you talking about? There is no pattern to learn. The prices do not follow the "same" pattern everyday. Fluctuations are totally unpredictable. Like we saw the price of bitcoin was around $6,700 last few days ago. Recently the price dipped below $6,000 USD to $5,900 USD and right now got back to $6,100 USD. All of these dipping are not following any common pattern.
