Look at the good part, this is a good moment to buy, because it didn't end in 2013, it was only the beginning. I doubt there will be such a crash though as Bitcoin is too popular right now.
In any capacity we cannot call it a crash, because bitcoin has taken a dip a little bit because of the Christmas, and it does make a sense because a week ago the price of the bitcoin was around 15k USD and after more demand in the market it raised to around 19k USD and now people are exchanging the bitcoin with the fiat currency to do some expenditures on the Christmas, so I think we cannot call it a crash.
