That's Elliot waves for you. Early on I noticed the rally/consolidate/flatline/drop cycle repeated over and over and over. A long "stable" period at the same (or slightly decreasing) price makes me nervous.
Of course the timespans in which the waves complete seems to increase logarithmically/exponentially so it makes sense that this flatline should last longer than the ones which preceded it. If BTC ever does see use as common currency it will likely be within extremely long flatline periods so it's probably a good thing to see log/exp increases in the cycle length.
