Covid has not affected Bitcoin and cryptocurrency in general but the whole financial market.
Bitcoin's positive effect from Covid is that Bitcoin was tagged as a possible safe haven for a pandemic and economic crisis like this happened in 2020. In 2020 alone, Bitcoin price pumped up from approximately 3,000+ to this December almost 20,000. More institutions have finally eyed and chosen Bitcoin as part of their portfolios as hedge for FIAT. More people tend to appreciate bitcoin and the cryptocurrency as a new way of money especially in this pandemic because physical cash can transfer the virus from one people to the other.
On the other hand, COVID-19 affected Bitcoin negatively only when it was in the 1st quarterly in the year when Bitcoin price dumped very hard with other finanicaassets to like gold, crude oil, even the forex market.
