The prices were down but that didn't last long because the pandemic contributed since people are locked in, they want to find ways to make money and it just so happens that some of them might've discovered bitcoin meaning that they are probably still using it today and they in turn contributed to the growth of bitcoin.
And it should not be surprising, at that time people were afraid that what we were seeing could put civilization at risk, even if the pandemic was bad and millions of people died the potential for the virus at the time was completely unknown and there was a possibility that it was way worse than what it actually ended up happening, so the markets in general were very nervous but it was natural that the crash happened and then as soon as it was obvious things will not be nearly as bad as what the markets thought the price grew up really fast.
The moment that these realizations started kicking into the minds of people, they also saw the potentials of Bitcoin even amidst this pandemic. That being said, I would say that the epidemic had and still is having a big impact on the lives of people and thus to Bitcoin as well. I just hope for the best, and that people will treasure and make wise decisions as they enter the crypto world.
