Market manipulation is currently floating through the market and your question that you will most likely put to realization will result with the satisfaction for the big players which are targeting the ones that are insecure and that are lowering the Bitcoins price with their dumps. The whale cannot crash the market alone but with the fear that is caused by its dumping, the whale can do everything. The result is in the end reinvestment of the big player in the same Bitcoin with the lower price and the accumulation for the future dump of the same. Be smart and keep your portfolio intact!
