Bitcoin's Power Law Model
Giovanni Santostasi discovered that Bitcoin's price moves in a straight line when plotted on a log-log graph (where price ticks on the Y axis, and dates on the X axis, get closer together as they go higher).
This suggests Bitcoin conforms to the Power Law, which appears many times in nature, for instance in the growth of city sizes.
Fair Price
According to the Power Law Model, bitcoin's price is always oscillating around its fair price, so when bitcoin's price is below fair it is "undervalued", and when above it is "overvalued".
The fair price is a surprisingly easy calculation. You just need to know A (1.057581e-16) and B (5.53999), which is what this site calculates. The model price on any day is then simply:
price = A * (days since the Bitcoin Genesis Block) ^ B
Bottom Price
The bottom price indicates the price which bitcoin will likely never go below, and is a set percent beneath fair price, based on price history.
