Just take a wider look to understand:
NASDAQ 100, last month + 8%, last year +60%
S&P 500, last month +6.4%, last year +47%
Bitcoin, last month -4%, last year +639%
Since the start of the COVID (in practice) to now, most indexed have exceeded their average returns, not to mention bitcoin. A movement such as this is a consequence and it may still be followed by more falls without meaning anything other than a profit taking and some caution around the ATHs.
More or less. What I am saying is that even if it is a steep drop, and may not be the last, the value of bitcoin is still quite strong and the fall may be linked to a profit taking. Many large investors are less bullish about next year than about last.
My personal take is that I am not selling even if the correction is stepper than this, since my plan is hodl for years the better part of my crypto. I do not use leverage nor run unnecessary risks, so I can keep on with my original strategy even if big drops happen.
