Imagine that a person does not have bitcoin, never used bitcoins, but that person is afraid to get a FIAT because he can get the virus. So how the hell is that person going to have bitcoin without leaving home? how is this person going to buy bitcoin without having money in the bank account? how did that person buy bitcoin without making KYC? And have you seen how high rates are when people buy bitcoin using a debit card?
^ It is a good question though, not all the times we can use bitcoin as payment when there are various numbers of good alternatives than bitcoin.
So, therefore, my answer is no. Pandemic has not intensified the usage of bitcoin because they don't have any connection, bitcoin continues rising up amends the COVID 19 situation. That was obvious that the economic crisis and bitcoin or other cryptos have not any correlated in the downtrend when the COVID virus almost killed our economic growth and now we are in a recession. Nevertheless, we should be thankful even bitcoin is not commonly worldwide payment used in but at least it is good for investment, as a safe haven.
