I don't think that the price went down because of corona. This virus literally kills the same number of people as normal flu every year. What's so special about it? Nobody counts normal flu victims every day to keep people up to date.
i think it has direct correlation with corona, fear and uncertainity now spreaded in any finance market. people know if they hold cryptocurrency meanwhile their job threatened due this virus , they prefer take save action and hold fiat.the speciality corona virus was it really disturb economy activity globally, not in single country.
