bitcoin down due to the effects of coronavirus cause the majority holder of bitcoin will sell when they entail costs for their needs at the time of virus outbreaks corona attack, everyone, of course, a lot of workers off due to virus corona they need the money for the life ahead they sell some of our valuable assets like bitcoin to meet needs in the future, not a few people who panic and sell all bitcoin they have.
This might be the cause, despite of thinking about the possible situation to happen such as expecting that more people will use bitcoin and its market price will increase, the opposite happened and that is people who have bitcoin started to sell. Well, we cannot blame them for their action as what is more important is to keep the family alive, and if bitcoin is the only way or asset they have to sell, it is a reasonable action to do so.
I have sold some bitcoins as well, but I still believe the its market price will be higher as soon as this pandemic starts to flatten its curve.
