It sounds like a rumor. I do not believe that the disease could affect the markets, especially when it happened in Europe (Italy) and not in China
Because it is a rumor since crypto journalist in are fan of doing it to gather more curious readers. The virus itself had nothing to do with the crypto economy and what we have experienced today is just the traders normal movement. I agree that the virus is spreading like a wildfire in some other countries but it wouldn't affect that much to the crypto price.
