I hope this will never happen of course, but for who have invested capitals, it may be a question someone have answered accurately to avoid an important loss.
You get worried when you don't properly understand how Bitcoin works, the bull and bear market cycle involed, the volatility and you go about doing investment. If you do, you should have learned to stomach the short-term price volatility and focus on your goal with Bitcoin, Meaning if you Bought Bitcoin to HODL for a long term, let's say you are holding for a period 5 years and More, then there's no need to worry about wether Bitcoin would fall or not ,just relax and wait for that time to come .
