I know the corona virus affected the price of bitcointhat led many people to sell out at that time but I doubt coronavirus occured just because of bitcoin. The existence of corona virus have nothing to do with bitcoin, their might be something the caused the virus to occur but bitcoin was not the target, this deadly disease caused ao many effects on important things that is very valuable to human life. It also affected the economy in general.
Because this had an impact on the economy in general within a period of several months, it also caused some people to sell Bitcoin that they previously owned in order to use the money from the sale for their own lives. Because everyone around the world already knows that when the corona virus hit the world, it started to be difficult for everyone to work and earn money, even though most people were still able to access the crypto market to trade and earn money so they could continue to live their lives as usual. So the influence may only be on the difficulty of making money, not on anything else because Bitcoin is not affected by that.
