The COVID-19 epidemic affected the economy, causing many factories to shut down, and people were advised to stay at home => the demand for oil decreased to 30 million barrels a day. Meanwhile, oil producing countries only reduce their output by 10 million barrels a day. The difference of 20 million barrels was the main reason for the sharp decline in oil prices.
In addition, the futures contract in the oil sector has caused oil prices to fall below $0/barrel at the end of April, not due to epidemics.
On the contrary, the more unstable the economy, the more demand for ownership and payment of BTC will increase. Therefore, I do not think that oil price will affect BTC price.
