It seems we have returned to the mean, but where will the price be in a couple of years? We are all fascinated by this question, by my estimates based on the past two years growth, I predict we can expect $2k in roughly 2 years and 2 months time. I have used the growth in USD transactions as a basis for the extrapolations in the chart. The price is extracted by dividing USD transactions by 200000, (many thanks to joe200 for this method)
In this maturing market it is clear we have continued network growth despite the falling price, however the price growth is not as rapid as in years past since it at these prices it is far harder to move the market.
One important aspect I have not factored into this extrapolation is the halving in 2016, perhaps we'll see fireworks from this but I'd rather be conservative in my estimates.
