Nobody can predict whether the coin price will increase or decrease.  There is no formula that will lead you to discover its price because if there is, many bitcoiners and investors are super rich by now.  The coin price randomly changes from time to time because this is part of its volatility in nature.  Instead for looking for the clue or formula, just try to be updated in crypto price and analyze the changes in market price.  Do not believe on the prediction of other people instead, analyze the result of your data gathered and try to predict it by yourself.
