I am hodling at least until mid summer of this year. And if the price stays down, then that would mean to me that I definitely missed the big opportunity at the 20K USD ATH.
You may go wrong as per what happened with bitcoin prices in previous years. Bitcoin went to $1200 in 2013 and then fell down to $180 in 2015 and then raised to $20,000 in 2017. So, you never need to worry on today's bloodbath as bitcoin prices are always tend to recover from any kind of downfall.
I am a long term holder. I preferred to hold even bitcoin prices touched some peaks from $220. I am targeting million dollar levels for bitcoins hence I am not basically bothering about in between time ups and downs.
