I don’t think Covid is anyhow related here. The price of Bitcoins depends on us the users only. If more people demand to buy the coin, then price goes up. If more people sell it, then price goes down. This is the never ending process. This happens as Bitcoins are limited in numbers and more bitcoins cannot be produced or created. This is just an excuse that covid really helped to boom the coin. Before covid Bitcoins were around 500$, but still it crossed 10k usd at that time. So this all is happening due to the concept of supply and demand.
