You should know better how bitcoin is volatile, I do not see anything strange about such oscillations in the price. We have seen it in the past, and it is difficult to expect some stability in the near future because it is obvious that the market can be easily manipulated. There are people who see bitcoin just as a way to make money, and almost $14k was a great opportunity for some profit, most people think "Why should I not sell when I bought at $4k?", and one of those with a lot of coins can move market with only one big dump.

3 months ago price was only $4000, do not forget how this bull run is started.
