That's completely wrong. Price doesn't come from end users who need BTC. 95% of BTC activity is trading and financial related transactions, payouts for mining etc. 100% of price comes from the 95% of trading. The remaining 5%, people doing legit transactions, sales, services. moneygrams are not discovarable in price so it has nothing to do with the currrent market price. Out of those 5% think how rarely they need to go to a discoverable source to buy it, once a month, one a year who knows but its nowhere near trading usage.
BTC now is a trader's tool. it follows the markets and news with a slight divergence when there is opposing activity in the news. the price goes down because people have less faith in the asset and the future market. when people have more faith in the markets and that particular asset it goes up as they are willing to pay more for it.
Long before the covid-19 outbreak, Bitcoin has been experiencing bull and bear market, varying from the market capitalization to huge amount of BTC that was stolen by hackers, Covid-19 has nothing to do with the rise and fall of BTC, if you say people are selling their BTC, it must be to a buyer that needs BTC, so it keeps revolving around, no BTC is leaving the crypto market, you should know that crypto is not a stabilized currency. Thank you.
