Many just didn't expect it that early.
But I sure hope we will see a rebound in no time, for now, the index of fear is pretty big, however, it shouldn't discourage us from our goals

It is not a fear index but only about the level of panic that is happening to most people who still hold Bitcoin until now. But on the one hand I am also still convinced of a huge recovery in the price of Bitcoin because at this time Bitcoin enthusiasts are still much more than others so we all should not panic or be afraid of the current decline in the price of Bitcoin. Because this year Bitcoin still has the potential to return to its highest price so for now Bitcoin holders must be more patient in waiting for this.
I am waiting for a big pump instead of panicking at this time. We have no reason to panic right now, the market needs a dump before the big pump. From my perspective, Bitcoin is preparing for a long journey. We may see the Bitcoin market turn green in a few days and see a new ATH that is much higher than your expectations.
The market has given us a big opportunity to buy. The sudden drop below $90k was completely unexpected for me and I was happy. Because it was a great opportunity to increase my holdings which I did not miss at all and you should not either. For an investor, this is not a time to panic at all. Rather, you need to focus on using every opportunity honestly.
