Bitcoin seems to be regressing to the mean with the latest bull run. On a logarithmic view, a linear or even exponential upward trend can appear as a gradually flattening or asymptotic curve (the white line that bisects the highs and lows). This trend is identified by smoothing out the price history with a geometric "best fit" and with trend lines (in dark green)...
50 day moving average has previously provided an important threshold while bitcoin is preparing for a big move up. The recent movement around that MA seems to mirror previous behaviour, and therefore it may suggest the uptrend is not exhausted yet.
