I think the rapid dropping of price is due to some people that until now still selling their bitcoin in low price because they want to cut their losses due to continous fluctuation of the almost all cryptocurrency in the world market.
I think they affect the price we have to keep quiet in bitcoin so we can make sure they will have a great chance today and tomorrow. it's boring but we have to learn about it. The whale is one of the greatest enemies of the crypto holders.
I think because of the bitcoin whales. they manipulate bitcoin fluctuations in other words they have control over bitcoin prices. bitcoin is discarded as it exists. so we have to wait what their next mood is.
