This depends upon the circumstances surrounding the reason on why the price of BTC dropped.
As for me personally, I would definitely purchase more BTC and HODL it for long-term. Any opportunity that makes its price lower in the market is also an opportunity for me to earn them. Another thing, I do think that people are taking for granted the technology of the blockchain and its application in the world. That is why I do think that prices of BTC will definitely skyrocket AGAIN in the upcoming future.
I do also believe that the necesseties of hodling or selling a bitcoin once a huge price correction happens again was it's all depend upon the circumstances of the sorrounding and of course primarily, does your family needs a money matter in the next few months. I am admitted that bitcoin do help me alot to overcome these pandemic we have encountered worldwide and its great to think that despite the pandemic bitcoin made its way to top, to reach its new ATH but i do still have the fear that i couldn't accurately utter that bitcoin will always in good value as time passes by.
