I am not convinced that the Corona virus can have such a dramatic affect on the Bitcoin price. This virus have been around for months now and the Bitcoin price was stable. We even had two huge positive announcements, with both India and South Korea accepting Bitcoin as a commodity/currency.  

This is looking more like price manipulation prior to the Halving, because the whales know the Halving will have a further positive impact on the price and they want to scare the "weak hands" into selling their coins to make a bigger profit.  

                                                    There is nothing negative driving this huge price drop.
