OP's lines look like they are hash-rates due to the rather smooth exponential look of them, some additional data may give them the more fine grained squiggles. Hash rates ultimately have nothing to do with creating value (though some idiots think they do), thus I conclude OP's model is worthless.
This is just an
unsubstantiated personal opinion.
Difficulty affects ones ability to mine coins verses buy them, thus the higher the difficulty the more one adds to the demand side of a finite supply. So it should be expected that the law of supply and demand will impact the price.
Well after trying to reconcile the auto-correlation in the model it turns out that after careful analysis, hash rates are indeed caused by high prices and not vice-versa according to the data,.. this, for me, only makes it more interesting!
Can you tell my what your model shows for dicember 2014?
