• We compute the Hurst exponent by means of the Detrended Fluctuation Analysis method, using a sliding window in order to measure long range dependence. We detect that Hurst exponents changes significantly during the first years of existence of Bitcoin, tending to stabilize in recent times. The Hurst Exponent is equal to 1 minus alpha divided by 2. Since alpha is assumed to range between 0 and 2, the Hurst ranges between 0 and 1. To recap, the Hurst Exponent measures the degree to which a time series, either aggressive strongly to a longer term mean or cluster in a particular direction.

Series A and B are two realizations of the exact same processes, as b is identical in both cases. Series C illustrates a perfect Brownian motion, with H = 1/2. A hurst exponent, H, between 0 to 0.5 is said to correspond to a mean reverting process (anti-persistent), H=0.5 corresponds to Geometric Brownian Motion (Random Walk), while H >= 0.5 corresponds to a process which is trending (persistent). The hurst exponent is limited to a value between 0 to 1, as it corresponds to a fractal dimension between 1 and 2 (D=2-H, where 0 < H < 1). What is the Hurst Exponent? It's a measure of a time-series' feedback on itself, or its memory. If the exponent is found to be 1/2, the time series is moving "truly" randomly, and towards 1 or 0 it is either displaying positive feedback or negative feedback, respectively. Arlene S.
