As I have said earlier, I will not post here again (because of a deletion to a post of mine) to comment on bitcoin or to make prediction of bitcoin prices.
The following is an exercise in curve fitting, fitting an exponential curve (y = A exp(kx)) to the price data of bitcoin in the recent 1 year using simple regression analysis. The curve is extrapolated into the future. I do not comment if such a curve fitting is of any use. Readers may decide if such a curve fitting extrapolation means anything.
