I imagine bitcoin staying as it is after the pandemic has subsided. There's no big factors that would greatly affect its price anyway so I don't see how it's price will drop or rise drastically. Unless a huge buy or a huge sell is made by one or more people. This could cause a big change in the price and altogether alter bitcoin's value. Then again at the end of the day these man-made factors cannot be put into the equation beforehand because they're very unpredictable.
There will be selling after the pandemic, there is no telling however when the pandemic will end. The economy will still struggle even after the pandemic though, you can imagine people selling their properties for less than 50% of the price they bought. If the ones selling their BTC are selling for USD which is also collapsing that its purchasing power is diminishing it will just be pointless.
