Anything can happen, however I think Bitcoin will be difficult to repeat the 2014 history.
It still goes up and down steadily, just the time will be long or short. The truth is that it keeps on rising over time. No need to worry!!! Let's see the price of Bitcoin this Christmas (2018).
FYI I am not worried, I just want to get the best entry point as much as possible.
I believe it will bottom at $6-$7k then rebound beyond the ATH of $20k this year.
