You're a star, gbianchi!
Please fit us a function for the price dependent on time
P(t) = function (time-offset)
Thanks.
here the function you request:
P = e^(((days from 01/01/2012) * 0.0067) + 1.641))
example: price at 31/12/2014 =
days from 01/01/2012 to 31/12/2014 = 366 + 365 + 365 = 1096
P = e^((1096*0.0067) + 1.641) = 7976.06132258175
So mas o menos, roughly speaking, approximately, rule of thumb:
Price = 6 * Exp (0.2 * months since 1/1/2012 )
Correcto?
Example new years eve 2014 --> 2015
could be 8000 ~ 6 * Exp (0.2 * 36)
and NOW
was: 729 ~ 6 * Exp (0.2 * 24)
