I do not think there will be a direct link between the Corona epidemic and the Bitcoin price. The more it can affect other markets, the more it will affect the crypto market. Not much.
There is a link otherwise we wouldn't have seen the ugly drop a few weeks back which will remain part of bitcoin's history for years to come. People who buy bitcoin are not any different from people who buy stocks or invest in other markets. Most will obviously join the markets to make profits and when catastrophe or crisis strikes... They will always try to cash out in preparation for the worst.
