Although the possibility of a price decline of up to $ 10K could occur, but I believe that bitcoin will continue to increase when the negative issues like now end, so I personally would prefer to hold it even though it takes quite a long time,because I believe if bitcoin has strong fundamentals and it will not be difficult for bitcoin to be able to reach its highest price again.
The volatility is certain, but we all can't pinpoint exactly where the bottom will actually stop. The possibility of a price drop to $10K is possible if we analyze the chart, but still we are only playing between two possibilities - up or down.
If you are sure to be a long term holder then I can probably advise you to buy any dip as I think it is a very good option. But of course you'll be fine if you actually just want to hold it in without wanting to accumulation.
