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.
But if you look at the charts that existed in the previous year then sometimes the movements are very similar and in accordance with what happened before. But thinking on a bitcoin price tradition then everything could happen so we can not be sure bitcoin prices in some future time. All we can do is speculate and do a Bitcoin price guess. All existing predictions will not be sure as they all depend on many people who have Bitcoin.
