In 2017 at least, Bitcoin has been showing us very consistent and clear 60 day Cycles. The sample size is relatively small, but the consistency is impressive. The chart suggests the next Cycle Low to occur around Jan 12th, and if the parabola has broken here, then a natural 50% bull market retracement would be the type of "blood in the street" event that a bull market would throw us at this point in its evolution.
Stay sharp and nimble, remember that markets never move in one direction all of the time. Even a retracement back to the $5,700 preserves the major bull market trend and allows for sentiment to be reset.
thank you for the analysis and the best of luck in trading!
