I assumed that this period of time there are a pot of people again panic sell because os the corona virus. The Bitcoin price drops and so as the the other altcoins. I dont know why does people always sells when sudden phenomenon is occuring. But for other people this is a great opportunity to invest because not just bitcoins and cryptocurrency is decreasing but the stock market too. So for me just for me this is a great time to buy stocks buy cryptocurrency and just wait for a long run. I do not panic when you have a lot of patience and you are not depending into all this as your main source
For simple reason's they are all want to secured thier asset by having it in fiat when they know that there will be a negative effect on the market.
Its a wise decision to other 's and wait only when the price decline so they can make a buy back and use the money they sell in high price. Its normal thing in trader's they are not holders so every negative news they make a move earlier to other's and use that opportunity to earn.
