You wake up tomorrow and Bitcoin has plunged all the way to 50k - what do you do?

Imagine if you were to wake up tomorrow and Bitcoin took a big hit during the night and is all the way down at 50k. You can't believe your eyes at all but yep - prices are dropping and have even reached 45k for a bit before rising again. Still, everyone's panicking like crazy, especially on this subreddit and posts about not to panic are flooding /r/CryptoCurrency.

What would you do?

Just HODL? Or try and sell in case another huge hit comes, which everyone in this sub is fearing? Just wondering about what you guys would do in case that happens as an ATH can induce quite a lot of fear because prices are most likely going to go down again. Lemme know????
