There might be other reasons why bitcoin have increased it's price because viruses like corona will only affect the mortality of a human being not the market.
It has had quite an impact on the Chinese economy with how very large cities have seen a dramatic decline in productivity and directly economic growth. In this case it makes sense that there is a negative effect on the market.
In crypto it's nonsense. People shouldn't hope that the Corona virus is causing the price to increase because if that was actually why the price went up, the price would give back its gains when the situation around the virus calms down.
You definitely don't want Bitcoin to behave like a safe haven because it would miss out on the mad gains during a decade long equities bull run. Gold as safe haven performed very poorly in the last decade.
