Every time Bitcoin went parabolic, it will crash and have it corrections. The length of the crash and consolidation period depends on many factors.
One of the factor is how fast the price can recover and maintained at higher prices, we can see this during the early 2013 crash when Bitcoin recovers quite fast and went to another parabolic move at the end of 2013. However, the longer Bitcoin unable to recover, or the deeper it goes down, the longer it will take for Bitcoin to recover to its all time high. The 2011 crash took almost 20 months from Bitcoin . The 2013 crash took 3 years for Bitcoin to recover. Notice how the price of Bitcoin drift lower and lower as it unable to make a new important high to bring it back to the game. Also notice how when the RSI goes below 70, Bitcoin went into a much longer consolidation period. The RSI did not dip below 70 for the early 2013 crash.
The 2011 crash was catastrophic 90% drop from all time high while the two 2013 crash was a 80% drop from the all time high.
So, whatever Bitcoin -5.40% trajectories will be in the future of 2018 will depends on its ability to recover and rebound. If Bitcoin drops 80% or 90% and unable to rebound, we might be into a multi year bear market. However, if Bitcoin can rebound from the current level (7-8k) and immediately go to 15k, then this consolidation period may be shorter and we can expect to see another all time high by end of this year or early 2019.
February, March and April 2018 will be an important months because the candles and closing of these candles will guide us the trajectories Bitcoin will take in the future.
I will update this at the end of every Month closing.
