The table below shows the cyclic patterns of bitcoin’s price increases.
For special effect we’ve used the 260 day cycles of the mayan calendar.

Notice how we corrolate the elapsed days in the “days” column against the prices for the following dates: 1-aug-2017, 23-dec-2017 and 9-sep-2018.
We’ve mapped the prices over 12 cycles. Over the most recent 9 of these, we find over 7 of these cycles an average increase per cycle of 5x or 500% and in 2 cycles we find losses of 65% and 62%.
Extrapolating the average gains of x5 we get a price of over 35k for both bitcoins showing up for the next check-point coming up on the 9th september 2018.
If these projected prices also correlate with elapsed days, then the results will most elegent, but time will  only tell if the correlation holds true for the next set of prices.
