Some are panicking, some are happy amidst the recent decline in Bitcoin. 
Therefore, if you are a trader determine the value you can afford to bear. However if you are a long term investor buy as much as possible in the current conditions. We have seen the price from 100k down to 60k and back to 1++k until it reaches its highest point. This does not mean that Bitcoin will not experience the same thing. My advice is to get out of the market if you cannot withstand the fluctuations.
