Panic selling always happen. Usually it starts when a person or group of persons shorted anything from one price at a big volume, from that point other people will start to think that there is something bad that happened and they will follow shorting the asset. It is a normal phenomenon that happens when people want to take profit because they think the price is high enough and then when the price starts to fall they will buy again at a discounted price.
