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.
Bitcoin is having a lot of problems just to touch the price of 10000 again and you want bitcoin to touch the price of 100000 by the year of 2020? I am not saying that it is impossible, in fact I think that by that time bitcoin will begin to recover but I'm not really sure that such a price is possible so soon.
I agree it is hard to predicted these price high and possibly it reach more years to happen. Their is always uncertainty of the price in bitcoin. So, I think their is an increase on bitcoin value but not that high.
