Personally, I would buy more depending on my budget and HODL. There is no point of selling your bitcoin when it is at its lowest. It would not be profitable, depending on you investment. It will be the perfect time to buy for us. And expectedly, since most of us have rhe same mindset, bitcoin will rise up again.
Some are in depth and at risk of losing everything they have, some people just have to sell
And every wave of investors brings some of those that buy high and sell low.
