Uuhm, the outbreak of Coronavirus is affecting every stocks in the market, and assets . Stocks like gold, silver, other precious metals and other things have all been affected by the outbreak. You might be right about that, its likely that a lot of people have stopped trading right now. The decrease in price made everything to be worse, a lot of people might be afraid to be trading at this time because they fear they might lose their money.
But, if you still check the cryptocurrency market you will notice that there are still lots of people that are buying, the buying rate I saw on Coinbase today is 72%, so people are still buying. Long term traders (Hodlers) would see this as an opportunity to buy at a low rate.
They still have confidence when choosing to invest and when the market is down, it is a great opportunity for people to invest again. I think that at any price, there will be buyers and that is what every investor wants when joining this market. I think the epidemic may only affect the psychology of investors and when this is over, things will soon stabilize. Personally, I'm still optimistic and still invest in some of the coins that I consider to be potential.
