Bitcoin is following the same pattern as it followed in 2013 October bull run where the price jumped from 100 USD to 1200 USD and crashed again to subsequent years to come. The bear market after 2013 bull run continued for 1 and a half year till February 2015 where the price bottomed out. All the while during the bear market the price of the bitcoin tested a downward trendline making lower highs each time and ultimately breaking the trendline. It kept in range from March of 2015 to December of 2015 after which the price started making higher highs and eventually started the bull run of 2017. My hypothesis revolves around the concept of lengthening market cycle of bitcoin and I see bitcoin price doing the same thing it did in 2015 but taking more time to complete each of the above steps. I believe that price of bitcoin is currently following a downward trend on the weekly chart. Based on previous concept, I believe that bitcoin price will try to break the downward trendline in near future(2020). If it succeeds, the price will move in range all through the year 2021 after which the price will start making higher highs and marking the start of a new bull market during the year 2022 and ending the bull market in year 2023.
