It's not prediction it's only statistics for last years. Every bull market bitcoin grow approximently 16x
2011 year : (1$-30$) ,
2013 year: (100$ - 1149$)
2017 year : (1000$ - 20000$)
Last bull market was ended in january and on the statistic bull market continues approximently one year. Bearish maret on the statistic continues approximently 10 mounth and if look on past periods, next bull market begin in october - december 2018. Therefore based on past years can to make computation next price bitcoin:
2020 year: 6500$ x 16 = 104 000$ ?
Guys it's only statics as per past years, don't accept this how accurate prediction future.
This is your own personal analysis and assumptions judging from past bitcoin price movement, but the point I will disagree with is where you predicted $104000 price in 2020 because since the price of bitcoin is highly volatile it will be a false to state an exact amount bitcoin will be in the future.
